Abstract
The dc power supply can effectively improve the reliability of the output voltage and current through parallel connection, but at the same time, there will be an increase in the output current voltage harmonic compared to a single dc power supply. For this problem. In this paper, the dc step-down chopper circuit is taken as an example to analyze the output current under the double-pulse width modulation mode. Through calculation and experimental verification, it is shown that the modulation mode used in this paper can realize the suppression of specific subharmonics.
