본문

This paper proposes second-order SDSDM (Space Dithered Sigma-Delta Modulation) to suppress the harmonic spikes in power

conversion. PWM (Pulse Width Modulation) normally operates with a fixed switching frequency, which causes power spectrum to be

concentrated at multiples of the switching frequency. The proposed scheme is confirmed in the DC/DC converter. The experimental

results show that the proposed method provides improved performance in reducing harmonic spikes caused by PWM while maintaining

the low current ripples.
