Abstract
A controller for operating a multilevel electric power inverter circuit. The controller is configured to generate and apply to the plurality of switching elements switch signal waveforms, the switch signal waveforms comprising a first control signal for causing an energy storage device to be series connected with a direct current source and a load or an alternating current source and charged to a predetermined value proportional to a voltage of the direct current source, and a second control signal for causing the energy storage device to be disconnected from the direct current source and series connected with the load or the alternating current source, thereby causing the energy storage device to be discharged.
