Abstract： When conducting scientific research on instrumentation，a stable and wel-performing power supplyoften makes theexperimentachieve twicetheresultwithhalftheefort.Atpresent，thedomesticmarkethasalargedemandforhgh-precision four-quadrantpowersupply.Basedonthisbackground，ahigh-voltagendhigh-precisionfour-quadrantpowersuplybasedon fuzzyPIDis designed.Inthis paper，the methodofcombining hardwareclosed-loowithsoftwareclosed-loopisadopted，which greatlyimprovesthe effctiveness ofthe measurementresults.The software controllopuses 24-bitADCchipADS12xx and 24- bit DACchip PCM17x.The hardwareclosed-loop is realizedbybuildinga hardware PIDcircuit.Through experimental tests， theoutput voltage meets expectations，anditiscontinuouslyadjustableinthefour gears ofmediumvotageandhighvoltage，and the voltage ripple is below 0 . 4 V. （20
