TL;DR: This work presents an overview of single-phase boost-chopper-derived power-factor-correction rectifiers and a methodology is derived to compute these harmonics in order to facilitate the analysis and performance evaluation of the converters.
Abstract: This work presents an overview of single-phase boost-chopper-derived power-factor-correction rectifiers. Converters are presented for several control strategies in continuous and discontinuous current mode operations. The presentation highlights the main characteristics of the converters and underlines harmonic content over a wide frequency range. A methodology is derived to compute these harmonics in order to facilitate the analysis and performance evaluation of the converters. Based on this methodology, a comparison is conducted in order to highlight advantages and drawbacks of the most popular converters and control strategies. A table is given where main converter critical parameters are summarized in order to help the designer, in converter and operating mode selections. Practical results are provided to validate the modeling technique.

TL;DR: In this paper, the authors present the monolithic integration of a gate drive power supply with the power switch to be driven, and demonstrate that the solution does not require any main power switch technological process modification-leading to a cost effective solution.
Abstract: Main power switches such as metal oxide semiconductor field effect transistors or insulated gate bipolar transistors have reached very high performances from an electrical point of view. If their electrical characteristics are getting closer to physical limits, there is still a lot to do to improve their functionalities. The paper presents the monolithic integration of a gate drive power supply with the power switch to be driven. The operating principle is discussed to demonstrate that all needed components for this function can be integrated with the power switch. It is also demonstrated that the solution does not require any main power switch technological process modification-leading to a cost effective solution. Modeling and analysis comments are provided in order to clarify and to present operating principles and possible design constraints. Finally, the realization itself is presented. Prototypes are used to highlight the interest of such function.
