| Summary: | 碩士 === 國立成功大學 === 電機工程學系碩博士班 === 96 === 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%.
