Abstract
A multilevel power converter and method for transforming DC power from a DC source into AC power for an AC load are provided. The converter is composed of a half-bridge inverter, a switching cell, and a controller configured for controlling operation of the half-bridge inverter and the switching cell. The half-bridge inverter and the switching cell are connectable to the DC source and the AC load. The switching cell is composed of first and second pairs of switches forming first and second branches in parallel, first and second capacitors connected in series in a capacitor branch connected between the first and second branches, and a pair of back-to-back connected switches in a third branch, the third branch connected to the capacitor branch and connectable to the AC load.
