| Abstract: | With the induction of the international electromagnetic compatibility (EMC) directives, there is an increasing awareness of the electromagnetic interference (EMI) problems of switching power electronics. The principle, spectral characteristics analyses of the randomised modulation technique have been proposed in the paper. The theoretical and measured results indicate that novel entirely random switching schemes employing the twin random factor can suppress conducted EMI in the power converters in which the harmonic spectrum can be dispersedly and continuously distributed effectually. |
