First, different topologies of power converters are considered and the ringing choke converter (RCC) is chosen according to the required specifications of the targeting system. After that, a power conversion system is proposed based on the operation of RCC to provide sinusoidal output voltage with fixed frequency. The oscillation principles of the energy-storage circuit and the control mechanism of the feedback signals are discussed in the thesis. The oscillation frequency is determined by natural resonance between the capacitance in the energy-storage circuit and the leakage inductance on the primary side of the transformer. At the same time, the feedback signals are utilized to control the switch devices such that the oscillation can be sustained and the sinusoidal output voltage can be obtained on the secondary side of the transformer. Furthermore, if the area of the converter is preferred to be decreased for integration, a ring oscillator is presented to generate a square wave output with fixed frequency. By connecting the ring oscillator to a capacitor and a transformer, it can also transmit energy into the human body using sinusoidal wave and can be applied to the wireless transcutaneous power conversion system.

碩士 === 國立臺灣大學 === 電子工程學研究所 === 95 === This thesis focuses on the wireless transcutaneous power conversion system and its goal is to develop a converter which converts DC input voltage to sinusoidal output voltage with constant frequency. First, different topologies of power converters are considered and the ringing choke converter (RCC) is chosen according to the required specifications of the targeting system. After that, a power conversion system is proposed based on the operation of RCC to provide sinusoidal output voltage with fixed frequency.
The oscillation principles of the energy-storage circuit and the control mechanism of the feedback signals are discussed in the thesis. The oscillation frequency is determined by natural resonance between the capacitance in the energy-storage circuit and the leakage inductance on the primary side of the transformer. At the same time, the feedback signals are utilized to control the switch devices such that the oscillation can be sustained and the sinusoidal output voltage can be obtained on the secondary side of the transformer.
Furthermore, if the area of the converter is preferred to be decreased for integration, a ring oscillator is presented to generate a square wave output with fixed frequency. By connecting the ring oscillator to a capacitor and a transformer, it can also transmit energy into the human body using sinusoidal wave and can be applied to the wireless transcutaneous power conversion system.
