An inverter-charger combination includes plurality of first and second switching elements, a capacitor, and a dual active bridge, connected in parallel to one another. The first and the second switching elements are connected in series to form switching subassemblies that are disposed in parallel and are connected to an AC source. Each of the first and the second switching elements has a first and a second contactor, and, when the first contactor is open and the second contactor is closed, an electric current flows from a rechargeable energy storage system (RESS) in direct current form to a load in AC form through the switching subassemblies to provide power to the load, and when the first contactor is closed and the second contractor is open, an electric current flows from the AC source in AC form to the RESS in DC form through the switching subassemblies to charge the RESS.
