SINGLE-CYCLE REVERSE-RUN VOLTAGE CONVERTER Russian patent published in 1995 - IPC

FIELD: secondary power supply sources. SUBSTANCE: converter is manufactured in accord with single-cycle circuit with reversal of rectifier diode and transformer separation of circuits of supply and load. It is fitted with one or several identical regeneration circuits connected in parallel to each other each including capacitor, diode and choke. Decrease of dynamic losses of power in transistor key is achieved thanks to its unblanking with zero collector current. Choke forms collector current and determines charge current of capacitor. Transistor key blanks with zero collector voltage obtained with the aid of charge capacitor. Switching on of two or more regeneration circuits gives possibility of formation of curve of collector current of transistor key close to rectangular one and of transfer of part of power to load during forward run which reduces installed capacity of transformer and transistor key. EFFECT: reduced installed capacity of transformer and transistor key. 3 cl, 2 dwg
