Aimed at the hard-switching issues associated with the traditional zero current switching (ZCS) switched capacitor converters (SCCs), a zero voltage and zero current switching (ZVZCS) DC-DC SCC based on an LC auxiliary network is proposed, which can achieve zero voltage switching (ZVS) for all switches throughout the entire operating range. Under certain conditions, it can also simultaneously achieve both the ZVS and ZCS, significantly reducing the switching losses. On this basis, an in-depth investigation into the impact of dead time on converters is conducted, revealing a quantitative relationship between dead time selection under different load conditions and converter loss distribution. Subsequently, a design methodology for key parameters of auxiliary networks based on dead time is put forward. Finally, based on the proposed ZVZCS SCC, a 24 V DC-12 V DC experimental prototype with 100 W was constructed with a peak efficiency of 99.07%, thus validating the correctness of the theoretical analysis.

针对传统零电流开关ZCS(zero current switching)的开关电容变换器SCC(switched capacitor converters)的硬开关问题,提出了1种基于LC辅助网络的零电压电流开关ZVZCS(zero voltage and zero current switching)DC-DC SCC,使得所有功率开关均可实现全范围的零电压开关ZVS(zero voltage switching),并且在一定条件下可以同时实现ZVS和ZCS,大大减小了开关损耗。在此基础上,深入研究了死区时间对变换器的影响,揭示了不同负载条件下的死区时间选取与变换器损耗分布之间的定量关系,进而提出了基于死区时间的辅助网络关键参数的设计方法。最后,基于所提出的ZVZCS开关电容变换器,搭建了24 V DC-12 V DC、100 W的实验样机,实现了99.07%的峰值效率,验证了理论分析的正确性。

针对传统零电流开关ZCS(zero current switching)的开关电容变换器SCC(switched capacitor converters)的硬开关问题,提出了1种基于LC辅助网络的零电压电流开关ZVZCS(zero voltage and zero current switching)DC-DC SCC,使得所有功率开关均可实现全范围的零电压开关ZVS(zero voltage switching),并且在一定条件下可以同时实现ZVS和ZCS,大大减小了开关损耗。在此基础上,深入研究了死区时间对变换器的影响,揭示了不同负载条件下的死区时间选取与变换器损耗分布之间的定量关系,进而提出了基于死区时间的辅助网络关键参数的设计方法。最后,基于所提出的ZVZCS开关电容变换器,搭建了24 V DC-12 V DC、100 W的实验样机,实现了99.07%的峰值效率,验证了理论分析的正确性。

Aimed at the hard-switching issues associated with the traditional zero current switching (ZCS) switched capacitor converters (SCCs), a zero voltage and zero current switching (ZVZCS) DC-DC SCC based on an LC auxiliary network is proposed, which can achieve zero voltage switching (ZVS) for all switches throughout the entire operating range. Under certain conditions, it can also simultaneously achieve both the ZVS and ZCS, significantly reducing the switching losses. On this basis, an in-depth investigation into the impact of dead time on converters is conducted, revealing a quantitative relationship between dead time selection under different load conditions and converter loss distribution. Subsequently, a design methodology for key parameters of auxiliary networks based on dead time is put forward. Finally, based on the proposed ZVZCS SCC, a 24 V DC-12 V DC experimental prototype with 100 W was constructed with a peak efficiency of 99.07%, thus validating the correctness of the theoretical analysis.
