Abstract: A welding-type power system than includes a power supply, a DC power bus, an energy storage device, and a bi-directional converter. The bi-directional converter configured to connect the DC power bus to the energy storage device, and further configured to convert power from the DC power bus to the energy storage device to charge the energy storage device, and to convert power from the energy storage device to the DC power bus in response to a power demand on the DC power bus. The bi-directional converter further configured to balance the DC power bus. A controller is configured to control the duty cycle of the bi-directional converter in order to balance the DC power bus, and control the flow of power between the energy storage device and the DC power bus.
