POWER CONVERSION DEVICE

摘要

A control circuit (11), during a positive period in which current flows from a power conversion apparatus to a load, causes a second snubber capacitor (Crn) to discharge by controlling a second auxiliary switch (Srn) to be turned on while a second main diode (Dn) is turned on, and during a negative period in which current flows from the load to the power conversion apparatus, causes a first snubber capacitor (Crp) to discharge by controlling a first auxiliary switch (Srp) to be turned on while a first main diode (Dp) is turned on.
