摘　　要：新颖的Buck-Boost型正弦交流稳压器电路结构,由输入周波变换器、高频储能式变压器、输出周波变换器以及输入、输出滤波器构成,它能够将一种不稳定的劣质交流电变换成另一种同频稳定的优质正弦交流电。本文对Buck-Boost型正弦交流稳压器的电路拓扑、控制方案等进行了分析研究。原理试验结果表明,Buck-Boost型正弦交流稳压器具有较强的负载适应能力、优良的稳压性能和高质量的输出正弦波形等优点。Novel circuit configuration of the Buck Boost mode regulated sinusoidal ac power supply is constituted of input cycloconvertor, high frequency storage transformer, output cycloconvcrter, input and output filters. The unsteady input AC voltage with high harmonic can be transformed into the steady sinusoidal voltage with low harmonic. The circuit topology and control strategy are analyzed in this paper. Principle test results show that the Buck-Boost mode regulated sinusoidal ac power supply has many advantages such as strong load adaptability, perfect vohage-regulation performance and good output sinusoidal waveforms.
