Āhuatanga

He kōwhiringa ngā pūnga hiko whakarewa kotahi me ngā pūnga hiko whakarewa takirua.

Tono

1. I roto i ngā tono hikohiko mana, ko ngā pūnga hikohiko snubber te kawenga mō te whakaiti i te pokanoa hikohiko mā te pupuri i te tangi o te ngaohiko me te iahiko.

2. Kua whakamauhia ki ngā Kōwae IGBT, hei whakaiti i te hiko hiko korekore, ka tukuna ngā pūnga Snubber i roto i ngā pito whirihora hei whakamahi i ngā mahi maha.
