| Abstract(in English) | We studied small-size and low-loss output voltage control circuit for isolated power supply with magnetic resonance. By using this circuit, low-loss output voltage control can be achieved without isolated device, such as transcoil and photocoupler, for output voltage feedback from secondary side to primary side because power consumption in primary side is restrained with output voltage control by switching the secondary circuit. As a result, the isolated power supply circuit can be very small. In this research, frequency characteristic of series-series(SS) type is derived, and circuit architecture and behavior of output voltage control is proposed by using frequency characteristic. And, the proposed circuit is verified by simulation. |
