Embodiments of the invention provide methods and apparatuses for
concurrently eliminating or substantially reducing two or more switching
losses in an inverter switching circuit. Embodiments of the invention
concurrently reduce multiple types of switching losses under hard
switching mode and soft switching mode for active switching devices and
diodes. In one embodiment of the invention, the voltage across a
switching device is substantially reduced during switch turn-off and/or
turn-on time, and also maintained at a substantially reduced level
throughout some or all of the tail current loss time of the switching
device. Other methods and apparatuses are also described.
