基于阻抗网络单元且减少有源开关的单相Buck-Boost AC-AC变换器系列

In this article, a family of single-phase buck-boost ac–ac converters based on impedance network cells with reduced active switches is proposed. Unlike the converters presented so far, voltage range and frequency regulation are achieved by only five switches and one switching cell. The inherent commutation is achieved without snubber circuits, a safe commutation method, or splitting the circuit st...
