Welcome to POWERSIMTOF
Christophe Basso's Webpage
After three long years of extensive work on this project, my new book entitled Transfer Functions of Switching Converters - Fast Analytical Techniques at Work with Small-Signal Analysis is available for purchase via the links given below.

The book starts with a smooth introduction to switching cells, going into the details of the first steps of linearization and small-signal modulation. You will then learn how the PWM switch model was derived and how to apply it to the basic structures operated in fixed switching frequency and various operating conditions like continuous and discontinuous modes in voltage- or current-mode control. The model is extended to other control schemes like quasi-resonance, constant on- and off-time converters, all with an associated small-signal version. The following chapters explore the founding structures like the buck, the boost and buck-boost cells, naturally covering their isolated versions like forward or flyback converters with many variations (push-pull, half- and full-bridge, phase-shift, interleave etc.). The last chapter deals with more complicated structures like Ćuk, Zeta, SEPIC and LLC.

The book represents an ideal companion for the young or seasoned engineer willing to study and stabilize her or his switching converter. Finally, BSEE, MSEE or Ph.D students will also find many useful descriptions and methods they can later apply during their studies or when facing their first industrial projects.

The most famous catalyst of the modern LGBTQ rights movement—the Stonewall Inn riots of June 28, 1969—was not a cisgender gay male event. It was led by trans women, specifically transgender women of color. Marsha P. Johnson (a self-identified transvestite and drag queen who later embraced her trans identity) and Sylvia Rivera (a Latina transgender activist) were at the vanguard.

When patrons fought back against police harassment that night, it was the most marginalized members of the "gay community"—homeless trans youth, drag queens, and sex workers—who threw the punches. For years following Stonewall, mainstream gay organizations (like the Gay Activists Alliance) actively tried to distance themselves from "street queens" and trans people, fearing they were too radical, too poor, or too "visible" to be palatable to straight society.

Sylvia Rivera famously interrupted a gay rights speech in 1973, shouting: “You all tell me, ‘Go away. You’re too radical. You’re hurting our image.’ ... I’ve been beaten. I’ve had my nose broken. I’ve been thrown in jail. I’ve lost my job. I’ve lost my apartment for gay liberation.” Her words echo today as a reminder that the comfort of the "LGB" sometimes came at the expense of the "T."

As transgender visibility has grown, so has a debate: does the trans community belong within LGBTQ culture, or is it a distinct movement that should sometimes operate autonomously? Some trans activists argue that cisgender gay and lesbian people cannot fully understand trans struggles, necessitating trans-led organizations. Others emphasize that the forces opposing trans rights (religious conservatism, state violence, medical gatekeeping) are the same that target all queer people.

Increasingly, the answer is both/and: trans-specific organizing (e.g., Trans Lifeline, the Transgender Law Center) works alongside broad LGBTQ coalitions to achieve legal and social change.

The relationship between the transgender community and the broader LGBTQ (Lesbian, Gay, Bisexual, Transgender, and Queer) culture is often described as a shared history with distinct threads. While the "T" has been a formal part of the acronym for decades, the journey toward genuine inclusion and mutual understanding has been complex, evolving through eras of solidarity, marginalization, and, more recently, a re-centering of trans voices within queer liberation.

Transgender community is not a subcategory of LGBTQ culture—it is one of its beating hearts. To separate them is to misunderstand queer history. The trans community has taught LGBTQ culture that gender is not binary, that self-determination is sacred, and that liberation cannot be achieved by appealing to the most comfortable members of society. Conversely, LGBTQ culture offers trans people a lineage of rebellion, chosen family, and the radical hope that exists outside the closet.

As one activist put it: “There is no queer liberation without trans liberation. And trans people cannot be free until all queer people are free.” In that interdependence lies the true promise of the rainbow.

The T in the Rainbow: The Transgender Community & LGBTQ Culture

The relationship between the transgender community and broader LGBTQ culture is one of deep-rooted history, shared struggle, and vibrant mutual influence. While the acronym brings together diverse identities, the transgender experience offers a unique lens on gender that has fundamentally reshaped how we understand identity in the modern world. A Legacy of Resistance The most famous catalyst of the modern LGBTQ

Transgender and gender-nonconforming people have often been at the front lines of the movement for LGBTQ equality. Historically, key moments of resistance were led by trans women of color, such as Marsha P. Johnson and Sylvia Rivera

during the 1969 Stonewall Riots. These activists didn't just fight for trans rights; they fought for the collective liberation of all queer people. Pioneering Visibility: In the 1950s and 60s, figures like Christine Jorgensen

brought the concept of medical transition to the public eye.

The "Transgender" Label: The term emerged as an umbrella in the 1960s and 1990s to replace older, often pathologizing language, eventually becoming a permanent fixture of the "LGBTQ" acronym by the early 2000s. Shared Culture vs. Unique Struggles

While LGBTQ culture is built on shared values and expressions, the transgender community faces specific hurdles that are often more intense than those faced by cisgender gay or lesbian individuals. LGBTQ+ - NAMI


Today, the transgender community is experiencing a level of visibility that was unimaginable in the Stonewall era. From Pose to Disclosure, from Laverne Cox to Elliot Page, trans narratives are in the mainstream. However, this visibility has come with a ferocious political and cultural backlash aimed specifically at trans people—often separate from general homophobia.

Many outsiders assume that the "T" was a late addition to the acronym, but this is a historical misconception. The transgender community was not an invited guest to the LGBTQ movement; they were the architects of its foundation.

The transgender community is not a separate wing of the LGBTQ movement; it is the backbone. The same force that allows a young lesbian to hold her wife’s hand in public—the defiance of assigned destiny—is the very force that allows a trans woman to live authentically.

LGBTQ culture without the transgender community would be like a rainbow without violet: incomplete, dimmer, and historically inaccurate. As the political winds blow colder against trans rights, the broader culture is being tested. Will the "LGB" stand by the "T" as fiercely as the "T" stood for them at Stonewall?

The answer, for those who truly understand the history, is a resounding yes. Because when one part of the family bleeds, the entire rainbow turns red. Today, the transgender community is experiencing a level


Key Takeaways:

If you are looking for a featured platform for mature trans content, Trans-Mature is a highly-rated site that focuses specifically on performers in the 35+ age range. Key Feature: Curated "Mature-Only" Content

Unlike general tubes that mix all age demographics, Trans-Mature is built as a niche "feature tube" that highlights older trans women. Its main features include:

Verified Performer Profiles: Many videos are linked to official performer profiles, ensuring you are seeing actual mature trans models rather than mislabeled content.

High-Definition (HD) Categories: The site prioritizes high-quality resolution (1080p and 4K) for its featured "Hot" and "Trending" sections.

Advanced Filter System: You can filter content specifically by "Milf," "Mature," or "Granny," which is more precise than standard tube site tags.

Community Rankings: A "Top Rated" feature allows users to vote on the best mature content daily, which populates the homepage with the most popular videos of the moment.

For a broader variety, sites like Shemale.com also offer a dedicated "Mature" section that features daily updates and professional-quality productions.


The modern LGBTQ rights movement is often traced to the Stonewall Uprising of 1969 in New York City. What is less commonly taught is that transgender people—especially trans women of color like Marsha P. Johnson and Sylvia Rivera—were central actors in the riots and subsequent activist organizations. Rivera co-founded Street Transvestite Action Revolutionaries (STAR) , one of the first groups focused explicitly on homeless trans youth.

Yet, even within early gay and lesbian liberation groups, trans people faced marginalization. Some feminist and lesbian organizations of the 1970s excluded trans women, viewing them as inauthentic or as infiltrators—a painful legacy that continues in some "trans-exclusionary radical feminist" (TERF) circles today.

Free SIMPLIS Simulation Files: when writing this book on transfer functions, I have extensively used SIMPLIS to confim the results obtained with Mathcad and SPICE were correct. The many hours spent in simulating transfer functions of various converters lead me to aggregate all the circuits in ready-to-simulate templates which, for most of them, can work on the free demonstration version Elements. From simple dc-dc cells to more complex isolated converters operated in current- or voltage-mode control and controlled in fixed frequency, phase shift, COT, FOT and so on, you will find in these files converters that are fully compensated with an automated macro for computing type 2 or 3 compensation parameters. The description PDF is here while a ZIP of all the converters is here.

Mathcad calculation files: I have used many sheets to verify my calculations and illustrate the book examples. I have gathered 42 files described here and made them available for a small fee for company/professional individuals (150 USD or 140 Euros) and students/hobbyist (60 USD or 50 Euros). The files work with Mathcad 15 and include auto-toggling CCM/DCM compensation sheets for flyback and forward converters operated in current-mode. I will transfer the compressed file via a specific link to your address. Please to proceed, thank you.
