提出了一种输入并联、输出串联的高电压转换比交错升压变换器。通过引入耦合电感和二极管电容技术，变换器可以进一步扩大电压增益。由于采用交错结构，可以显著降低输入电流纹波，减轻电磁干扰问题。给出了一台200w样机的测试结果，效率达到了93.5%以上。
A high voltage conversion ratio interleaved boost converter is proposed with connecting input in parallel and output in series. By introducing coupled-inductor and diode-capacitor techniques, the converter can further extend the voltage gain. Because of the interleaved structure, the input current ripple can be reduced significantly, alleviating the electromagnetic interference problem. The test results of a 200 W prototype are provided and high efficiency above 93.5% is achieved.
