چکیده
Fast switching techniques at high frequencies are employed for quick charging and energy conversion in electric vehicle (EV) power converters. Electromagnetic interference (EMI) noise is produced due to the fast-switching process, which may result malfunctioning degraded EV performance. In this work, a digital chaotic pulse width modulation (DCPWM) technique-based EMI mitigation process has been applied elementary positive output super lift Luo (EPOSLL), two-stage cascaded boost (TSCB), ultra-lift (ULL) converters, comparison study conducted with reduction levels as per electromagnetic compatibility (EMC) standards. The duty cycle varied from 0.5 0.67 get desired voltage an input of 10V achieve ratings 40 W 80 various load conditions. A total 4 dBV (3 V) 15 (10 mitigated above-said Simulation results based on spectrum density hardware fast fourier transform (FFT) voltages analyzed. According findings, ULL converter more acceptable applications than EPOSLL TSCB DC-DC

متن کاملPrediction of the Conducted EMI from DC-DC Switched-Mode Power Converters
This paper presents theoretical estimation of the conducted electromagnetic emissions from a SMPS, based on Fourier analysis. The theory is applied to a buck converter. The comparison between the theoretically estimated and measured EMI shows that the CM EMI was well predicted. Up to 3 MHz the measured DM noise was much lower than the predicted one, which could be because of unknown DM noise so...

متن کاملA New Intelligent Controller for Parallel DC/DC Converters
In this paper, the immune controller, is used to control the paralleled DC-DC converters. A PID controller is first applied and its coefficient is optimized using an intelligent (PSO) algorithm. Immune controller is then added to PID controller and an immune PID controller is formed. Two methods have been suggested to determine non-linear behavior of immune controller. In the first method, an e...
