| Abstract |
This paper presents a practical evaluation of a quasi-resonant circuit which creates zero-voltage switching condition for power inverter with minimum voltage stress. This quasiresonant circuit can pull down the dc link voltage momentarily to zero for zero voltage inverter switching without setting the dc link voltage above the nominal dc link voltage - even under no-load condition. The soft-switching approach has the advantages of lossless, stressless and snubberless inverter switching and can be incorporated into many well-established PWM switching schemes. An experimental prototype circuit has been developed and tested. Experimental results have confirmed the operating principles of the quasi-resonant soft-switched inverter. |
