摘要：The present invention relates to a high efficiency three-level inverter apparatuscontaining both bipolar and field effect transistors. An embodiment of a modified controlscheme is also presented whereby transistors are modulated differently for eachquadrant of output voltage-current phase. This embodiment of a modified control
scheme allows efficient switching of field effect transistors without additionalfreewheeling and series diodes.
