单级Buck-Boost逆变器单模式运行的新型开关策略

Generally, single-stage buck-boost inverters consist of distinct circuits operating individually in buck/boost or positive/negative modes, the latter definitely leading to crossover distortion in the output current. This paper proposes a switching strategy that changes the bimodal operation of a single-stage buck-boost topology to a single-mode inverter. This is due to the consequent voltage gain ...
