Abstract

An output of a first converter for switching a rectified line current and an output of a second converter for switching a direct current are added together so that an efficiency, a power factor, a holding time, and a ripple characteristic can be improved. Further, the power supply apparatus can be made compact and the cost for manufacturing the apparatus can be reduced. A flyback converter type output circuit and a forward converter type output circuit are used in a parallel manner so that a transformer having a high efficiency can be used, and it becomes easier to control the apparatus.
