24-PHASE CONVERTER DESIGNED BY SUCHKOV Russian patent published in 2012 - IPC H02M7/08 

FIELD: electricity.

SUBSTANCE: 24-phase converter may operate in two modes: that of a rectifier and that of an inverter. Operation in the uncontrolled rectifier mode during usage as semiconductor diode chokes proceeds as follows: two chokes always operate: one of the twelve chokes of the cathode group (the one having the largest anode potential) and one of the twelve chokes of the anode group (the one having the least cathode potential). That is why the mean value of current flowing through the choke I_c is equal to 1/12 of the mean value of load current I_o:I_c=1/12 I_o. During a period each choke is activated once. Two chokes operate simultaneously (one from the anode group and the other - from the cathode group) instead of eight as with the prototype.

EFFECT: mean value of choke direct current as well as loss of voltage and power in the course of the converter operation are four times less than with the prototype.
