Transistor Switches Quasi-Control in Quasi-Resonant Pulse Converters

摘要

Features of zero current and zero voltage switching quasi-resonant pulse converters control are analyzed in this paper. Ways to reduce dynamic losses in transistor switches are described. Reasons for changing parameters of currents and voltages in resonant circuits of these converters, as a result of which their resonance frequency changes, and consequences of this fact are justified. Principles of transistor switch automatic quasi-control are considered, whereby simplifies to synthesize of control systems and reduces dynamic losses in it.
