本論文針對非接觸式供電的應用場合，研製三相/單相換流器；電路分為前級的三相功率因數修正器與後級的換流器兩個部份。非接觸式供電技術是利用變壓器感應耦合的原理，設計無接觸方式的能量轉換，可使負載與電源之間的電能傳輸無需傳輸線的連接，可以廣泛應用於各種特殊狀況下。本研究計劃的目標，主要是設計一轉換器電路，此轉換器接受三相市電並將之整流成直流電壓源，供給後端的DC/AC轉換器，輸出高頻的交流電壓源。三相AC/DC的部份以三相昇壓式轉換器搭配六次諧波注入法實現；後級的DC/AC轉換器以積分控制全橋相移實現。本轉換器電路的設計重點，將著重於高功率因數的設計。最後，本論文完成一500W高功率因數交流三相/單相換流器之設計與模擬，並以實作結來驗證本論文之理論與設計之正確性。在3ψ220V交流輸入時，系統滿載效率為69.2%，功率因數為0.978，總諧波失真為20.3%。

This thesis presents the three-phase to the single-phase inverters with front-end power factor correction (PFC) circuit for the non-contact power supply. By using the induction coupling of the power transformer, the technology of the non-contact power supply, transfers the energy from the supply to the load without a transmission line, can widely be utilized for particular applications. The purpose of this thesis (research work) is the high power factor design of the AC-to-DC converter that can rectify the three-phase power connected to grid system to the DC-to-AC inverter for the AC output voltage source with high-frequency. The three-phase AC-to-DC converter is the three-phase boost converter which can be accomplished by using the method of the six-order harmonic injection. Meanwhile, the DC-to-AC inverter is the full-bridge phase-shift circuit that can be achieved by using the method of the integrator control.
Finally, the design and the simulation of the 500W three-phase and single-phase inverter with high power factor can be completed by the validation of the experimental results. Under 3ψ220V input and fully load, the efficiency is 69.%, power factor is 0.978, current THD is 20.3%.
