| Abstract: | The output voltage ripple of digital switch power supply is larger than that of analog power supply.An effective way to decrease the output voltage ripple of digital switch power supply is introduced.Taking advantage of coupled-inductor filter network,the requirement of low ripple is achieved without decrease of the dynamic performance of power supply.Based on AFS600 field programmable gate array(FPGA),a digital DC/DC power supply flat is established,and control system on chip of power supply is implemented.The correctness of low ripple design is verified through experiments,and the output voltage ripple is reduced by 50%. |
