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 official operating system provided by HTC. It comes with the Sense user interface and pre-installed carrier apps.

Used with SP Flash Tool for clean unbricking and manual downgrades or upgrades. Essential Prerequisites

When the phone was under active support, HTC rolled out several official updates. These updates, delivered OTA, were designed to improve performance, squash bugs, and enhance security. While comprehensive changelogs from that era are difficult to find, user reports and tech blogs from the time have documented a few key releases.
