CCVM-DCVM边界模式定频LCC谐振变换器设计
Design of Fixed Frequency LCC Resonant Converter Operating in CCVM-DCVM Boundary Mode
摘要
Abstract
While inherit many advantages from traditional LCC resonant converter, fixed frequency LCC resonant converter greatly reduces its design difficulty of magnetic elements and simplifies design procedure of EMI filter. However, adapting improper parameters in such implementation leads to serious problems such as high voltage/current stress and/or the loss of soft switching operation. So far, an appropriate parameter design procedure is still demanded for fixed frequency LCC resonant converter. Based on the power analysis of fixed frequency LCC resonant converter, this paper proposed a parameter design procedure which makes the converter operate under CCVM-DCVM boundary mode, limiting the voltage and current stress of the converter while maintaining the soft switching condition under rated working operation. And by adapting the fundamental harmonic approximation the system is equivalent to a linear circuit. Through the linear circuit, the soft switching condition is derived. Furthermore, power analysis is given to unveil the relationship between the power of elements and element parameters, based on which a clear parameter design procedure is derived. The time domain simulation and experimental results show the validity of the theory and parameter design procedure in this paper.关键词
