Abstract
An insulated power supply apparatus includes an upper arm transformer which has a primary side coil and a secondary side coil, a lower arm transformer which has a primary side coil and a secondary side coil, and a power supply control section which has a voltage control switching element and an integrated circuit which turns on or off the voltage control switching element. At least one of the upper arm transformer and the lower arm transformer is adjacent to the power supply control section when viewing a surface of the substrate from a front thereof. An electric path transfers output voltage of the secondary side coil of the transformer adjacent to the power supply control section, to the integrated circuit. The integrated circuit turns on or off the voltage control switching element to perform feedback control so that the output voltage detected via the electric path reaches a target voltage.
