一种减少受控开关数量的单相多电平六桥臂AC-DC-AC变换器

This paper proposes two unidirectional single-phase ac-dc-ac converters with a reduced number of controlled switches composed of two three-leg converters connected in series. The proposed converters allow us to feed the load voltage with sinusoidal voltages with constant amplitude and frequency and to operate with sinusoidal grid current with a high power factor. The converters can then be used as...
