MULTI-LEVEL INVERTER

摘要

The present disclosure relates to a multi-level inverter capable of performing a bypass operation without adding any separate module. The multi-level inverter includes a first capacitor and a second capacitor coupled in series to each other, a plurality switches for generating a multi-level output voltage by using a voltage charged in the first capacitor and the second capacitor and a plurality of diodes respectively coupled in parallel to the plurality of switches, a first output terminal and a second output terminal for outputting the output voltage, and a controller for switching a state of each of the plurality of switches to an on or off state according to one of predetermined bypass modes, thereby interrupting the output of the output voltage through the first output terminal and the second output terminal.
