Analysis of Line to Ground Fault in Inverter FED IM Drive System
Inverter configuration is presented for the Induction Motor drive. One inverter is design for the step-down voltage and the second inverter is designed for the step-up voltage. PWM use to provide the gate signal to the MOSFET in the circuit.The inverter and the induction motor used as industrial appliances, so it is important to monitor and analyse the fault of the inverter output. While doing the conversion of ac to dc and dc to ac using the power electronics device the harmonics exist. Due to the malfunction in the VSI and CSI the faults are introduced. The current waveform is taken from each phase and the spectrum is analysed. The harmonic analysis with the help of FFT transform is carried out for the short circuit as well as normal condition.The simulation of the VSI and CSI using MATLAB is compared for both conditions i.e. without fault and line to ground circuit faults.
