Iguqula isignali ephumayo ye-PWM yenjini ibe igagasi le-sine elibushelelezi elinevolthi ye-ripple eyinsalela ephansi, evimbela ukulimala kokuvala amajika kwenjini.Yehlisa ukwenzeka kwe-resonance okubangelwa amandla asabalalisiwe kanye ne-inductance esabalalisiwe ngenxa yobude bekhebula, susa ukugcwala kwemoto okubangelwa i-dv/dt ephezulu, susa ukulimala ngaphambi kwesikhathi kwemoto okubangelwa ukulahleka kwamanje kwe-eddy, futhi isihlungi sinciphisa okuzwakalayo. umsindo wemoto.
