基于变频-移相混合控制的L-LLC谐振双向DC-DC变换器
A L-LLC Resonant Bidirectional DC-DC Converter Based on Hybrid Control of Variable Frequency and Phase Shift
摘要
Abstract
Considering the development and application of the energy storage systems in DC distribution system, bidirectional DC-DC converters with high power conversion efficiency and wide adjustable range are required. According to the hybrid control of variable-frequency (VF) and phase-shift (PS), a L-LLC resonant bidirectional DC-DC converter was proposed in this paper. It not only has wide adjustable ranges of the DC voltage gain and the transmission power, but also can realize the zero-voltage switching for input switches and zero-current switching for output rectifiers simultaneously. That leads to a high overall efficiency. Operation behaviors and characteristics of the converter under single VF or PS control were described. Then the rationality of the hybrid control was proved in theory, and an easy implementation was given. The experimental results of the prototype confirmed the validity of the theoretical analysis as well as the superior performance of L-LLC converter in operational efficiency and adjustable range.关键词
