THREE-PHASE ELECTRICAL RECTIFICATION CIRCUIT DEVICE AND THREE-PHASE ELECTRICAL RECTIFICATION METHOD

摘要

A three-phase electrical rectification circuit device and a three-phase electrical rectification method, the circuit device comprising: a first coupling inductor (Ta) which is connected to a first phase in a three-phase electric power by means of a first inductor (La), so as to obtain a first alternating-current power supply; a first rectification and topology circuit which is connected to the first coupling inductor (Ta) and performs rectification of the first alternating-current power supply, so as to obtain a first direct-current output; a second coupling inductor (Tb) which is connected to a second phase in the three-phase electric power by means of the second inductor (Lb), so as to obtain a second alternating-current power supply; a second rectification and topology circuit which is connected to the second coupling inductor (Tb) and performs rectification of the second alternating current power supply, so as to obtain a second direct-current output; a third coupling inductor (Tc) which is connected to a third phase in the three-phase electric power by means of the third inductor (Lc), so as to obtain a third alternating-current power supply; and a third rectification and topology circuit which is connected to the third coupling inductor (Tc) and performs rectification of the third alternating-current power supply, so as to obtain a third direct-current output.
