Abstract:
1. A power conversion apparatus comprising: a power conversion circuit constituted of parallel-connected pairs of a high-side switching element and a low-side switching element connected in series; high-side driver circuits to drive the high-side switching elements; low-side driver circuits to drive the low-side switching elements; and a transformer to individually supply a voltage to drive the high-side switching elements to the high-side driver circuits, and commonly supply a voltage for driving the low-side switching elements to the low-side driver circuits; wherein the high-side switching elements are mounted in a row on a wiring board, the low-side switching elements are mounted in a row on the wiring board side by side with the row of the high-side switching elements, and the transformer is mounted on the wiring board on the side of the row of the high-side switching elements opposite to the row of the low-side switching elements.
