| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 99 === A novel voltage doubler rectifier with non-electrolytic capacitor for sustainable energy power converters is proposed in this thesis. By applying the proposed rectifier to two current-fed converters as application examples, a current-fed push-pull boost converter with voltage doubler (CFBCVD) and a dual inductor current-fed boost converter with voltage doubler (DIBCVD) are presented. In addition to inheriting the advantages of the current-fed boost converters, the presented converters feature reduced output capacitor current ripple and output voltage ripple. Consequently, long life film capacitor can be used to replace the aluminum electrolytic capacitor and the reliability of the power converter can be enhanced. These features make it desirable for high frequency, high efficiency, high output-voltage, and high reliability power applications, such as the sustainable energy source power system. In addition to the operation principle, theoretical analysis, and design considerations, three voltage doubler rectifier current-fed push-pull converters are implemented and compared with 150 kHz, 36~75V input and 400V/400W output specifications.
