While being series connected between a first DC link part (L1) and a second DC link part (L2), capacitors (C1,C2) are charged by a regenerative current from an inverter part (2). During discharge, first and second switching circuits (Q1,D11,Q2,D12) are turned on, whereby, while being parallel connected between the first DC link part (L1) and the second DC link part (L2), the capacitors (C1,C2) are discharged. |
