Abstract
An insulated power supply apparatus is for a power conversion circuit including at least one series connection of an upper arm switching element and a lower arm switching element connected in series to each other. The insulated power supply apparatus includes an upper arm and lower arm transformers for supplying a driving voltage to the upper arm and lower arm switching elements, respectively, and performs control such that the output voltage of a specific one of the secondary coils of the upper arm and lower arm transformers is kept at a target voltage.
