PROBLEM TO BE SOLVED: To provide a power conversion circuit for suppressing common mode noise and a power conversion device using the same.SOLUTION: A power conversion circuit 1 includes an inverter circuit 2, a controller 3, a clamp circuit 4, capacitors 61 to 64 and a connection member 7. The inverter circuit 2 includes input terminals 201, 202 and output terminals 203, 204. The controller 3 controls the operation of the inverter circuit 2 and the clamp circuit 4. The clamp circuit 4 short-circuits or opens the output terminals 203 and 204. A series circuit of capacitors 61 and 62 is electrically connected between the input terminals 201, 202. A series circuit of capacitors 63 and 64 is electrically connected between the output terminals 203, 204. The connection member 7 electrically connects the connection point 601 of the capacitors 61, 62 to the connection point 602 of the capacitors 63 and 64.SELECTED DRAWING: Figure 1 |
