摘要
为了增大工作频率,减小输出纹波,提出了一种四谐振参数(LCCL)谐振变换器。该变换器是在LCC谐振变换器的基础上增加了1个附加电感。分析了电流断续模式下LCCL谐振变换器的工作模态,并建立了数学模型。分别试制了基于LCC和基于LCCL的样机,并进行了对比测试。仿真与实验表明,与LCC谐振变换器相比,LCCL谐振变换器在提高工作频率的同时,不会增大电流应力与损耗,具有输出纹波小,输出电压调节范围大的优点。
In order to increase the operating frequency and decrease the output ripple,a resonant converter with four resonant parameters,LCCL resonant converter,was presented.This converter was based on the LCC converter with an additional inductor.The operation modes of LCCL resonant converter in discontinuous mode were analyzed,and the mathematical models were established.Two kinds of prototypes were made,one based on LCC converter and the other based on LCCL converter,and comparison tests had been carried on.Simulation and test results show that,compared with LCC resonant converter,LCCL resonant converter has the advantages of higher operating frequency,lower electrical stress,lower output ripple and larger voltage regulation range.
