分散式電源架構在現今的電源系統中已被廣泛使用,原因為分散式電源架構中後端多個隔離式直流對直流轉換器,經由架構的變化,能同時解決多個不同輸出電壓及功率需求。
本論文所製作及分析的電路架構,即可使用於分散式電源架構後端直流對直流轉換器中,選擇成本低及易實現的RCD式順向轉換器為電路主要架構,並採用了交錯技術以提升轉換器輸出功率,及降低輸出電容電流漣波量。
電路之分析及設計都將於論文中描述與探討,最後製作出輸出功率為200W的交錯RCD式順向轉換器應用電路,以驗證理論及可行性。
The distributed power architectures have already been used extensively in switching mode power supply. Lots of isolating DC to DC converters are connected in back-end of distributed power architectures with the different kinds of converter topologies, the different output voltages and power demands can be generated in the distributed dc power supply system.
In this thesis, the system analysis and circuit implementation of a forward converter with interleaved pwm scheme are presented. The RCD passive snubber circuit is adopted to reduce the voltage spike at the transformer primary side and reset transformer. The interleaved pwm scheme can reduce the output filter current and voltage ripple and also reduce the current stress of active switches.
Finally, a 200W prototype circuit is implemented and tested to verify the theoretic analysis and the feasibility.
