High voltage DC contactor with solid state arc quenching |
摘要 |
An arc quenching circuit senses initiation of an arc across the contacts of a contactor, commutates a capacitor discharge to the contacts that brings the contact voltage to zero for arc extinction and promptly recharges the capacitor to enable reoperation.
