一种应用于车载辅助电源的DC-DC变换器
DC-DC Converter Applied to Vehicle Auxiliary Power Supply
摘要
Abstract
The design of DC-DC converters which are applied to vehicle auxiliary power modules(APMs)is taken as a research object,the topology of a two-stage DC-DC converter consisting of a three-level Boost(TL-Boost)topology and a half-bridge LLC resonant topology is proposed,and its working principle is analyzed.The front-stage TL-Boost topology converts a wide range of input voltage into a stable voltage,ensuring the high-efficiency operation of the back-stage half-bridge LLC resonant topology.The feasibility and correctness of the proposed DC-DC converter were verified by establishing an experimental platform and carrying out relevant experiments.关键词
