<p>A power converter includes a battery having a positive terminal and a negative terminal, a first power input to receive AC input power, a second power input to receive DC input power from the battery, a first power output to charge the battery, a second power output to provide power to a load, a rectifier circuit coupled to the first power input, and a non-isolated single-stage power conversion circuit having an input and configured as a buck-boost converter. The power at the second power output is derived from the first power input and/or the second power input. The single-stage power conversion circuit is configured to convert an AC voltage to a DC voltage using a common energy storage element, and is coupled to the first power output and the rectifier circuit.</p> |
