Capacitor Snubber voltazy avo lenta ambongadiny

Famaritana fohy:

Manome karazana capacitor snubber rehetra ny CRE.

1. Kapasitera snubber manavao novolavolaina sy novokarin'ny CRE

2. Ny mpitarika amin'ny famolavolana sy famokarana kapasitera sarimihetsika.

3. Raha mila famaritana snubber miavaka ianao dia mankanesa any amin'ny foibe famolavolana anay hahazoana capacitor snubber namboarina manokana.

endri-javatra

Misy capacitors snubber metaly tokana sy capacitors snubber metaly roa ho safidy.

Fampiharana

1. Amin'ny fampiharana elektronika herinaratra, ny kapasitera snubber dia miandraikitra ny fampihenana ny fitsabahana elektromagnetika amin'ny alàlan'ny fanamafisana ny feon'ny voltase sy ny courant.

2. Napetraka amin'ny môdio IGBT, mba hampihenana ny inductance miparitaka, ny kapasitera Snubber dia omena amin'ny terminal azo amboarina mba hahafahana mampiasa azy amin'ny fomba maro samihafa.
