摘要

本論文研製一具正負增益之電力轉換器，以輸入-輸出轉移函數為出發點，提出一可應用直流與交流電源之新型轉換器來實現其電源穩壓之功能，主要藉由電容直流偏移位準、回授與前饋理論推導得到一電路架構最簡單與可升降壓的正負增益轉換器。轉換器之架構只有兩個雙向開關、兩個電容與兩個電感，並使用RENESAS M16C/29微處理器來實現雙向開關的驅動波形，使用四組脈波寬度調變配合休眠時間做控制以達到正負增益及減少電壓突波之效果。最後以模擬與硬體製作測試結果，驗證本論文所提系統之正確性與可行性。

This thesis presents the design and implementation of power converters with positive and negative gains based on the input-to-output voltage transfer gain. Based on the dc-offset, feedback and feedforward theories to systematically develop new power converters with a simple topology and positive/negative input-to–output voltage gain. The derived power converters includes two bi-directional switches, two capacitors and two inductors. To reduce the voltage spike, the proposed converter use the RENESAS M16C/29 microcontroller to provide four PWM driving waveforms with dead-time control. Finally, simulation and experimental results are presented the correctness and feasibility of the proposed approach in this thesis.
