碩士 === 國立高雄應用科技大學 === 電機工程系博碩士班 === 103 === The frequency of most AC power systems is 50Hz or 60Hz. However, 400Hz power systems are widely used in the aircraft, communications and vessels. If conventional converter input frequency and output frequency are not the same. You must use the AC-DC and DC-AC two-stage power converter to achieve frequency conversion function. If you can use a single-stage power converter and provide two different frequency AC power at the same time, it will improve the flexibility of application for power converter. This thesis develops a bi-directional 60Hz-400Hz medium frequency power converter, its circuit architecture consists of a single-stage power converter as a major converter, a DC port, 60Hz AC port and a 400Hz medium frequency port. The digital signal processor TMS320F28035PN is used to control the system. Finally, a hardware prototype will be developed and tested to verify the performance of the proposed 60Hz-400Hz medium frequency power converter.
