PROBLEM TO BE SOLVED: To provide a power conversion circuit capable of switching between power conversion between DC power and first AC power, and power conversion between DC power and second AC power, without using a mechanical switch.SOLUTION: A power conversion circuit 10 includes: a DC terminal Q0 for inputting and outputting DC power; a first AC terminal Q1 inputting and outputting first AC power; a second AC terminal Q2 for inputting and outputting second AC power; two bridge circuits B1, B2 connected in parallel between the DC terminal Q0; two transformers T1, T2 each having primary coils C11, C21 connected between the two bridge circuits B1, B2 and secondary coils C12, C22 connected between the first AC terminals Q1. Intermediate potential points of the primary coils C11, C21 of the transformers T1, T2 are connected with the second AC terminals Q2.SELECTED DRAWING: Figure 1 |
