PULSE CURRENT SUPPLY Russian patent published in 1997 - IPC

FIELD: converter engineering; power supply for electroflotocoagulators. SUBSTANCE: pulse current supply has first thyristor whose anode is connected to positive input lead, thyristor cathode being connected to anode of second thyristor whose cathode is connected to first output lead; it also has first series circuit set up of choke and capacitor; vacant lead of choke is connected to negative input lead; there are also diode, second series circuit set up of n capacitors; vacant plate of first capacitor of second series circuit is connected to vacant plate of first-circuit capacitor and vacant plate of second-circuit capacitor is connected to common point of connection of first and second thyristors; current supply has n thyristors; m thyristors are connected through anodes and n-m ones through cathode; common points of connection h and h-m groups of thyristors are connected to first output lead; cathode of each of m groups of thyristors is connected, respectively, to common point of connection of capacitor and choke of first series circuit; capacitor of first series circuit and that of second circuit, 1 through m-1 capacitors of second circuit; common point of connection of m-1 and m capacitor of second series circuit are connected to second output lead and anode of each of n-m groups of thyristors is connected to common point of connection of m through n capacitors of second circuit, n-2 additional diodes; diodes short out differentially 1 through n-1 capacitors of second series circuit. EFFECT: reduced power requirement for process conduction. 1 dwg
