Abstract
According to some embodiments, an electronic drive circuit is disclosed. The electronic drive circuit includes an energy storage device and a first bridge circuit coupled to the energy storage device. The first bridge circuit includes at least one leg having two switches. The electronic drive circuit also includes a transformer. The transformer includes a first winding coupled to the first bridge circuit and a second winding coupled to the energy storage device through a center tap. The electronic drive circuit further includes a second bridge circuit coupled to the second winding of the transformer. The second bridge circuit includes a pair of switches operable to conduct in both directions and block voltage in both directions. The electronic drive circuit additionally includes a DC bus coupled to the second bridge circuit and a controller, which is configured to buck or boost a DC voltage from the energy storage device to supply to the DC bus as well as buck or boost a DC voltage from the DC bus to supply to the energy storage device.
