Abstract :
The aim of this paper is to analyze and propose the installation of a cascaded dv/dt filter for PWM AC drive system with long feeding cable. The effects of installing single and cascaded second order dv/dt filters are investigated and compared. The investigated system is simulated by MATLAB/Simulink program and implemented to substantiate the effectiveness of a cascaded dv/dt filter. Both simulation and experimental results show that the system using the cascaded dv/dt filter can extend the cable length longer than the system using only a single dv/dt filter.
