本文主要再研製以相移全橋零電壓技術為基礎的高電壓DC/DC轉換器。在高電壓輸出全橋轉換器中,電路中所出現的振盪現象,通常跟二極體在逆向偏壓時的等效電容、變壓器的漏感與雜散電容有關。這些雜散的效應將會改轉換器的性能,尤其是當變壓器二次側為高圈數。本文主要是在探討變壓器的非理想特性對轉換器所造成的影響,並加入被動式緩振電路來抑制振盪的現象。電路架構是採用相移式脈波寬度調變控制方式來實現零電壓切換全橋升壓式轉換器,轉換器一共有五個轉換狀態,在文中有詳細推導及模型化。最後實際設計製作一部輸入電壓48V、輸出電壓為250V、輸出功率為500W升壓轉換器的實例,其實驗與模擬的結果跟預估極為相近。
In this thesis, a high-voltage DC-DC converter is proposed by phase-shift full-bridge zero-voltage-switching(ZVS) technique. In high-voltage output full bridge converters, the ringing occurring form the rectifier circuit is usually dependent on the equivalent capacitance of the diode in reverse bias, leakage inductance and winding capacitance of the transformer. These parasites effect can significantly affect converter behavior, especially for large number of secondary turns. This thesis focuses on effects of the transformer nonidealities, and the passive snubber circuits were use to damp the ringing. The circuit topology uses phase shift pulse-width modulation technique to realize ZVS full-bridge boost converter which has five conversion states. A design example of 500W power boost converter with 48V input and 250V output is examined. The results of the experiment and simulation are very close to predictions.
