Abstract
A multi-level switched capacitor boost inverter includes a series connection of a two-switched capacitor circuit, a source module and at least one one-switched capacitor circuit. Level-shifted pulse width modulation is used to apply gate pulses to the switches. The multi-level switched capacitor boost inverter uses only three capacitors and a single DC voltage source to generate thirteen voltage levels at load terminals with a voltage gain of three. The capacitors of the two-switched capacitor circuit are self-balancing. Additional one-switched capacitor circuits can be added in series with the inverter. Each additional one-switched capacitor circuit increases the number of levels and increases the gain by one.
