POWER CONVERSION CIRCUIT AND POWER-CONVERSION CIRCUIT SYSTEM

摘要

PROBLEM TO BE SOLVED: To perform power conversion between two selected ports in a power conversion circuit having four ports.

SOLUTION: A power conversion system 100 includes: a primary conversion circuit 20; a secondary conversion circuit 30; and a controlling circuit 50 to control the primary conversion circuit 20 and the secondary conversion circuit 30. The primary conversion circuit 20 includes: a primary full-bridge circuit 200 including a bridge having a primary coil 202 of a transformer 400 and a primary side magnetic-coupling reactor 204 to which two reactors are magnetically coupled; a first input/output port 280 formed between a positive and negative bus bars in the primary full-bridge circuit 200; and a second input-output port 290 formed between the negative bus bar of the primary full-bridge circuit 200 and a center tap 202m in the primary coil of the transformer. The secondary conversion circuit 30 includes the same structure as the primary conversion circuit 20.
