摘　　要：为降低成本、减少器件并保证电路安全运行,提出1种单相隔离型Δ源AC-AC变换器。新型变换器可以提供更宽范围的Buck-Boost输出电压,输入/输出电压可同相或反相,同时可抑制浪涌和谐波电流,提高电路可靠性。对所提电路的工作原理进行分析,推导得到各工作过程中主要元器件电压及输入/输出电压的关系式,并与其他改进的交流变换器进行对比,从理论上证明了新型交流变换器性能的优越性。根据所设计的参数搭建仿真模型和实验模型进行验证,仿真与实验的结果证实了理论分析的正确性与可行性。To reduce the cost and the number of components while ensuring the safe operation of the circuit,a single-phase isolatedΔ-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.
