GTO snubber capacitor i masini eletise eletise

Fa'amatalaga Puupuu:

Snubber circuits e taua mo diodes o loʻo faʻaaogaina i le fesuiaʻiina o taʻavale.E mafai ona faʻasaoina se diode mai faʻamaʻi maualuga, lea e ono tulaʻi mai i le taimi o le toe faʻaleleia.

Fa'aaliga

1. Mylar tape, Faamaufaailogaina i resini;

2. Ta'ita'i nati apamemea;

3. Tete'e i le maualuga voltage, maualalo tgδ, maualalo le vevela maualuga;

4. maualalo ESL ma ESR;

5. Malosi maualuga A'o.

Fa'atatauga

1. GTO Snubber.

2. Fa'aaoga lautele i mea fa'aeletoroni eletise pe a o'o i le pito maualuga o le voltage, o le puipuiga o le absorption pito i luga.
