Method of operating a multi-level switched capacitor boost inverter

A method of operating a multi-level switched capacitor boost inverter, comprising:

• generating, by a control circuit, a plurality of gate pulses using level-shifted pulse width modulation (LS-PWM);
• applying the gate pulses to a plurality of unidirectional semiconductor switches of the multi-level switched capacitor boost inverter;
• charging, by a DC voltage source, a pair of series connected capacitors of a two-switched capacitor circuit of the multi-level switched capacitor boost inverter;
• adjusting the gate pulses to balance each of the series connected capacitors to have a same voltage magnitude;
• charging, by the DC voltage source of a source circuit of multi-level switched capacitor boost inverter, a first output capacitor of a first one-switched capacitor circuit of the multi-level switched capacitor boost inverter;
• and
• generating a thirteen-level output voltage across a pair of load terminals equal to the charge on the first output capacitor,
• wherein the control circuit is operatively connected to the DC voltage source by a pair of load terminals, the first capacitor and the plurality of unidirectional semiconductor switches, wherein the control circuit is configured to generate drive signals to selectively operate the plurality of unidirectional semiconductor switches to provide an output voltage across the pair of load terminals.
