Abstract: A method includes charging a capacitor of a power inverter to a direct current (DC) input voltage from an input terminal of the power inverter. The capacitor has first and second terminals. The method also includes providing a first voltage at an output terminal of the power inverter at a first time by controlling one of either: an output switch that selectively couples the output terminal to either the first terminal or the second terminal; or a set of input switches that selectively couple the first and second terminals to either the input terminal or a ground terminal. The method further includes providing a second voltage at the output terminal at a second time by controlling the other of the output switch or the set of input switches.

Abstract: A method includes charging a capacitor of a power inverter to a direct current (DC) input voltage provided at an input terminal of the power inverter. The capacitor has a first terminal and a second terminal. The method also includes providing a first voltage at an output terminal of the power inverter at a first time by controlling one of either a set of input switches configured to selectively couple the first and second terminals to either the input terminal or to a ground terminal, or an output switch configured to selectively couple the output terminal to either the first terminal or the second terminal. The method further includes providing a second voltage at the output terminal at a second time by controlling the other of the set of input switches and the output switch.
