Abstract

The present disclosure relates to a multi-level inverter having a plurality of single inverter modules, the multi-level inverter including: a first controller providing a control signal to the multi-level inverter in response to voltage and frequency command based on detection of current and rotation speed of a motor; a second controller providing a control signal to the multi-level inverter in response to voltage and frequency command based on detection of current and rotation speed of a motor; and a plurality of single inverter modules converting an inputted AC power to DC power in response to the control signal from the first controller or the second controller, smoothing the converted DC power, converting the smoothed DC power to a three phase current in response to the control signal and outputting the three phase current.

Description

[0001] This application claims the prior filing date and priority of Korean Patent Application No. 10-2010-0120439 filed on November 30, 2010, which is hereby incorporated by reference in its entirety. technical field [0002] Teachings according to exemplary embodiments of the present disclosure relate generally to multilevel inverters with dual controllers, and more particularly to multilevel inverters with dual controllers configured to be composed of The first controller and the second controller in the control system are formed such that when the first controller fails, the second controller can drive the load. Background technique [0003] Generally, a predetermined driving system that drives a predetermined load uses a driver capable of driving the load. In addition, a controller is installed with the driver to control the operation of the driver so that the system accurately drives the load in response to an operation command. [0004] In a non-limiting example, in ...
