摘要： There is a problem in the prior semiconductor devices that energy recovery efficiency is low. According to one embodiment of the present invention, a power supply circuit includes an alternating-current signal synthesis unit including a plurality of alternating-current coupling elements having primary sides to which respective input alternating-current signals are input and secondary sides connected in series with each other, and a control circuit that outputs an input selection signal specifying a combination of the input alternating-current signals to be synthesized. The control circuit generates the input selection signal so as to maximize the output alternating-current signal synthesized by the alternating-current synthesis signal unit.
