Abstract

Many of the industrial applications require long power cables to connect the motor and Adjustable Speed Drive (ASD). The Pulse Width Modulated (PWM) inverter output voltage pulses and long cable length connecting the motor and ASD are the typical causes of over voltage inside drive. This high inverter output voltage (dv/dt) pulses and the impedance mismatch between motor and cable causes voltage reflection phenomenon. The reflected pulse creates over voltage condition that causes voltage stress inside the drive. This paper presents comparative study of over voltage mitigating methods for ASD, which includes RC clamp circuit method and LC filter method. The effectiveness of the clamp circuit method and LC filter method is verified by MATLAB/SIMULINK simulation. From the results obtained, it can be seen that the increase in length of cable increases over voltage and also RC clamp circuit is the simple and effective way to mitigate the overvoltage.
