    摘要: A power converter apparatus comprises a detection circuit, a control circuit and a time period generating circuit. The detection circuit detects whether a power device is in a short-circuit state. The control circuit sets, when the detection circuit has detected that the power device is in the short-circuit state, the power device in an inoperable state for a predetermined time period, and restores the power device to an operable state after the passing of the predetermined time period. The time period generating circuit defines the predetermined time period for setting the power device in the inoperable state, by measuring a time from the detection of the short-circuit state by the detection circuit.
