Abstract

A power supply device includes a power converter transformer, a coil, a first capacitor, and an energy regeneration circuit. The power converter transformer includes a primary winding and a secondary winding. The coil is provided on a primary side of the power converter transformer, and has a first end connected in series to a first end of the primary winding of the power converter transformer to store energy. The stored energy is regenerated in the first capacitor provided on the primary side of the power converter transformer by the energy regeneration circuit provided on the primary side of the power converter transformer.
