Original Abstract

This paper discusses the simulation of the cascaded H-bridge (CHB) multilevel converter for power coolant pump with the demand of high reliability and robustness. Multi-level converters are designed to control medium-voltage motors, energy conversion, active power filtering, and many other applications. First, an overview of the CHB converter, the method of control, and operation under fault conditions is described. The next part deals with the requirements of the application of the converter and the parameters of the simulation system. Then the 13-level multilevel converter is simulated during operation under normal conditions and during operation under abnormal conditions. If the cell is damage, it is bypassed by an auxiliary switch. The simulated voltages and torques were compared with each other. As a result, the converter is able to operate even with three faulty cells without interrupting the operation of the cooling pump.
