Iguqulela isibonakaliso semveliso ye-PWM yemoto ibe liza eligudileyo lesine elinombane oshiyekileyo we-ripple ripple, ukuthintela umonakalo kwi-insulation ejikelezayo yemoto.Ukunciphisa isenzeko se-resonance ebangelwa yi-capacitance esasazwayo kunye ne-inductance esasazwayo ngenxa yobude bentambo, susa i-motor overvoltage ebangelwa yi-dv / dt ephezulu, susa umonakalo wangaphambi kwexesha we-motor obangelwa yilahleko yangoku ye-eddy, kwaye isihluzo sinciphisa ukuvakala. ingxolo yemoto.
