GTO snubber capacitor i roto i nga taputapu hiko hiko

GTO snubber pūnga iahiko i roto i te hiko taputapu hiko Whakaahua Whakaatuhia

Whakaahuatanga Poto:

He mea nui nga iahiko snubber mo nga diodes e whakamahia ana i nga iahiko whakawhiti.Ka taea e ia te whakaora i te diode mai i nga titaha overvoltage, tera pea ka ara ake i te wa o te mahi whakaora whakamuri.
