摘要： A power supply device includes a failure determination means that detects, based on a current detected by a current detector, a failure of the switching elements of each of the chopper sections, and the failure determination means obtains values of the current detected by the current detector at the timing of falling edges of control signals to the switching elements of each of the chopper sections, determines the failure when the obtained current values differ from each other, and transmits a failure signal to a generation control means. When receiving the failure signal, the generation control means limits an output current from a generator in a way such that the withstanding current of a non-failed chopper section out of the chopper sections of the phases is not exceeded.

摘要： A power supply apparatus capable of setting a ripple current to be not more than an acceptable value regardless of an input voltage is obtained. The apparatus calculates switching frequency by a current detected by a current detector so that the switching frequency is set to be low if the current is large and the switching frequency is set to be high if the current is small. The switching frequency is set to be high if the input voltage is high and switching frequency is set to be low if the input voltage is low depending on a voltage inputted to an input terminal; and a switching element is controlled by restricting the switching frequency so that the switching frequency to be set by the current detected by the current detector is not lower than the switching frequency to be set by the input voltage.
