PULSE CURRENT POWER SUPPLY Russian patent published in 1997 - IPC

FIELD: converters, power supply units. SUBSTANCE: device has serial circuit of first thyristor 1, five capacitors 2-6 and first choke 7. Said serial circuit is connected to positive and negative input terminals. In addition device has five diodes 8-12 which by-pass capacitors 2-6, five thyristors 13-17. Two thyristors 13, 14 are connected by cathode s and three thyristors 15-17 are connected by anodes. Common points of thyristors 13-17 are connected to first output terminal. Anodes of thyristors 13, 14 are connected to plates of first capacitor 2 respectively; cathodes of thyristors 15, 17 are connected to common points of third capacitor 4 and fourth capacitor 5, fourth capacitor 5 and fifth capacitor 6 and common points of connection of fifth capacitor 6 and first choke 7 respectively. In addition device has second choke 18. Common point of connection of second capacitor 3 and third capacitor 4 is connected to second output terminal through second choke 18. Direct voltage power supply 19 is connected to output terminals. Load 20 is connected to output terminals of power supply unit. EFFECT: decreased power usage. 1 dwg
