Sreath SMJ-P

Ann an tagraidhean dealanach cumhachd, tha capacitor snubber ceangailte ri nód suidse mòr-làthaireach airson a bhith a’ lughdachadh inductance dìosganach uèirleadh dealain.

Bidh inductance parasitic ag adhbhrachadh àrdachadh mòr aig tionndadh dheth (nuair a tha an sruth air a bhacadh), agus ma tha àrdachadh mar sin nas àirde na ìrean co-phàirteach, tha draghan ann mu fhàilligeadh mar thoradh air sin anns a’ chùis as miosa.

Le bhith a’ cleachdadh togail ìosal inductance a-staigh, cùisean roisinn le cumadh roghainneil, agus crìochnachaidhean gnàthaichte, tha Sreath SMJ-P air an dealbhadh airson IGBTS atharrachadh gu luath agus faodaidh iad a bhith nan snubbers agus sìoltachain cuir a-steach àrd tricead gnàthach.
