A flyback converter using power-MOSFETs to achieve high frequency operation beyond 10 MHz <Abstract> In this study, we demonstrated an isolated-type flyback converter circuit for high-frequency operations. We estimated the high-frequency characteristics of passive devices in various conditions of a DC?DC converter circuit. We experimentally developed the isolated-type flyback converter circuit and evaluated the frequency response properties. In order to verify the fast-switching operation, the input voltages, output voltages, and currents of the converter were measured for both continuous and discontinuous operations. |
