摘要：

提出了一种三绕组耦合电感组成的交错并联基本单元结构,并演绎出了一系列适用于大电流、高增益或高降压变换场合的DC/DC拓扑族.采用有源箝位软开关电路无损地转移了漏感能量和消除了主开关管上的电压尖峰.在整个开关周期内,主开关管和辅助开关管都是零电压软开关动作,减小了电路的开关损耗.三绕组耦合电感的漏感限制了输出二极管关断电流的下降速率,抑制了二极管的反向恢复电流.总结了一系列采用三绕组耦合电感和有源箝位软开关电路组成的交错并联DC/DC变换器拓扑族.最后,设计了一台40 V输入、380 V输出的1 kW Boost变换器试验样机,实验结果与理论分析一致.
Abstract:

An interleaved basic cell with windingcrosscoupled inductors (WCCIs) was proposed. Then, a family of interleaved DC/DC converters was deduced from the basic cell for high current, high stepup or stepdown applications. The active clamp scheme was employed to handle the leakage energy and  suppress the voltage spikes on the MOSFETs, which was caused by the leakage inductance of the WCCIs. ZVT soft switching performance was realized for both the main and the clamp switches during the whole switching transition. The output diode reverserecovery problem was alleviated by the leakage inductance of the WCCIs. By employing the clamp capacitor shift rule, a series of interleaved DC/DC converters with WCCIs and active clamp circuits were summarized. At last, an interleaved ZVT Boost converter with WCCIs and active clamp circuits operating with 40 Vinput/380 Voutput was tested as an example to verify the effectiveness of the converters．
