The serial surge suppresses net which was constituted with mains filter
varistor and transient voltage suppressor was applied to the power supply port.The over-high residual voltage and potential danger to posterior circuit were found by experiment.Through analyzing experiment phenomena by using the traveling wave theory
it was found that coordination of the depress net was influenced by variation of resistance of switch power.The structure of suppress net was redesigned and it was proved that the new structure can improve suppress result obviously by experiment.
