双向CLLC谐振变换器的参数设计方法研究
Study on Parameter Design Method for Bi-directional CLLC Resonant Converters
摘要
Abstract
The bi-directional power transmission with a high efficiency and a high power density can be achieved by employing CLLC resonant converters.However,the traditional parameter design method is cumbersome and requires multiple iterations to obtain appropriate circuit parameters.To solve this problem,the working principle and characteristics of a bi-directional CLLC converter are analyzed,and a novel parameter design method is proposed.By considering the full range of soft switching,design index constraints and high-efficiency optimization conditions,the range of design parameters is narrowed and the design steps are optimized,thus effectively reducing the complexity of the converter parameter design process.Based on the demand for a 48～380 V/kW bi-directional DC-DC converter in industrial applications,specific parameter design steps and results were given,and a prototype was developed.The correctness and effectiveness of the proposed parameter design method was verified through experimental testing.关键词
