POWER CONVERSION DEVICE

In a power conversion device (1), a control unit (50) can perform cycle control in which switching control for switching operations in the order of a third operation, a first operation, the third operation, and a second operation is periodically repeated. The control unit (50) performs at least a first control for switching the third switching element (Q3) in the order of the OFF state, the ON state, and the OFF state during each first operation in the cycle control, and for switching the third switching element (Q3) in the order of the OFF state, the ON state, and the OFF state during a second operation. During each third operation, the third switching element (Q3) is maintained in an off state. 在电力转换装置(1)中，控制部(50)能够进行周期性地反复进行切换控制的周期控制，所述切换控制按照第三动作、第一动作、第三动作、第二动作的顺序切换动作。控制部(50)至少进行第一控制，所述第一控制在上述周期控制中的各个第一动作时按照断开状态、接通状态、断开状态的顺序切换第三开关元件(Q3)，在第二动作时按照断开状态、接通状态、断开状态的顺序切换第三开关元件(Q3)，在各个第三动作时将第三开关元件(Q3)维持为断开状态。
