Abstract

To comply with electromagnetic interference (EMI) standards, the electromagnetic noise generated by power electronic converters must be analyzed and suppressed since the switching frequency of the converter affects EMI noise. Conducted emission occurs in drive systems due to inverter parasitic capacitances and rapidly switching inverter output voltages. The EMI noise produced space vector pulse width modulation (SVPWM) inverter is calculated using MATLAB/Simulink simulation data. The unwanted common mode and differential mode signals produced by the inverter are captured using a spectrum analyzer and examined using short time Fourier transform (STFT). To mitigate the effect of EMI in the circuit and to comply with the standards filters are developed. The passive filter components are defined by the EMI standards attenuation requirements. The MATLAB simulation findings are confirmed and verified by hardware implementation.

Abstract

Nowadays, many firms have started producing electric vehicles (EVs). One of the biggest challenges to broad acceptance of electric vehicles is their limited range EVs. Forecasting future energy usage is one of the way to calculate the driving range. In this paper, a simulation model of the drivetrain has been developed to evaluate the energy flow of a vehicle for the given torque and speed conditions. The energy consumption of an electric vehicle is determined by the vehicle's attributes. Road torque, road speed, motor model, motor controller model, battery model, and PI controller are the primary components of the model. The overall resistive force offered by the vehicle, as well as energy consumption owing to resistive force during motoring and regeneration has been validated through the simulation results. Here, the vehicle model, Mercedes Benz Class C Saloon has been considered.
