基于“外套电路”的双极性高升压Zeta-Buck-Boost变换器系列

A family of bipolar high step-up zeta–buck–boost converters based on the “coat circuit” is proposed, which can be used to connect a low-voltage dc source and a bipolar dc bus. Like the basic zeta or buck–boost converter, it contains only one active switch, so its control method and drive circuit are simple to achieve. The conversion ratio of the proposed converter is effectively increased through ...
