基于非差分交流斩波器的无换流问题双极性Buck-Boost AC-AC变换器

This article proposes a new H-bridge structured bipolar pulsewidth modulation (PWM) buck–boost ac–ac converter based on the nondifferential ac choppers. The proposed converter can generate simple identical noninverting and inverting buck–boost voltage outputs by modulating one phase leg with single control duty ratio (${d}_1$ or ${d}_2$). It can also provide flexible identical noninverting and inv...
