Zusammenfassung:A method and apparatus for operating a current-controlled pulse width modulated inverter for driving a polyphase AC load includes using partial current feedback information, obtained from the inverter lower phase-leg switches and flyback diodes only, to regulate current flow in each phase of the load by synthesizing an analog feedback signal from the partial current feedback information.
