新型单相高频隔离型Delta源AC-AC变换器
Novel Single-phase High-frequency Isolated Delta-source AC-AC Converter
摘要
Abstract
To reduce the cost and the number of components while ensuring the safe operation of the circuit,a single-phase isolated Δ-source AC-AC converter is proposed.This novel converter can provide a wider range of Buck-Boost output voltage,and the input voltage and output voltage can be in-phase or out-phase.Meanwhile,the surge and harmonic currents are suppressed,and the circuit reliability is improved.The working principle for the proposed circuit is analyzed,the voltage values of main components in each working process are deduced,and the relationship between input voltage and output voltage is formulated,which is further compared with those of other improved AC-AC converters.The theoretical analysis proves the performance of the novel AC-AC converter.A simulation model and an experimental model were built according to the designed parameters for verification,and simulation and experimental results verified the correctness and feasibility of the theoretical analysis.关键词
