Abstract
A combined alternating current (AC) and direct current (DC) power converter is disclosed. In embodiments, the power converter includes an electromagnetic interference (EMI) filter, a bridge rectifier, and a boost converter. The EMI filter is configured to receive an electrical signal from a power source. The bridge rectifier is coupled to the EMI filter and includes at least four diodes arranged in a diode bridge configuration. The boost converter is coupled to the bridge rectifier and includes a switched DC path and a switched AC path. The switched DC path includes a DC transistor and the switched AC path includes an AC transistor. The switched AC path can also include one or more diodes and/or switching elements.
