“…This can be avoided by putting randomization range of switching frequency within the limit of ± one-third of central switching frequency. Chaotic PWM pulses can be generated by applying RCFMFD random scheme [13,14,15] along with pseudo number generator. Generation of random numbers can be done with the help of linear feedback shift register.…”

“…LFSR is a group of shift registers which use linear functions as a feedback mechanism to modify itself on each rising edge of the clock [14,15] which is shown in Figure 5. Here logic gates like XOR and XNOR gates are used as linear function to feedback the output bit to input bit.…”

Chaotic switching is a newly evolve randomization method which can suppress conducted electromagnetic interference generated within the DC-DC converter. It can suppress the spectral peaks present in the frequency band effectively by spread spectrum technique and can spread it over the wide range of frequency band implying EMI suppression. In this paper, a chaotic PWM technique based on RCFMFD scheme is generated through Field programmable gate array (FPGA) for suppressing the conducted electromagnetic interference (EMI) generated within the Luo converter. A hardware prototype of Luo converter was developed in order to analyze EMI reduction through FFT analysis by comparing both traditional periodic PWM switching and chaotic PWM switching. The results obtained from the hardware setup shows significant reduction of EMI with Chaotic switching as compared to traditional PWM switching for both boost and buck operation of Luo converter.
