Inrush Current Limiter Circuit


Posted on Jan 28, 2013

Q1 is an npn Darlington and Q2 is a prip Darlington. MOV1 is a metal-oxide varistor and R8 is an thermistor for limiting inrush current. This circuit limits ac line current to a load. When a predetermined interval has passed, RY1 shorts out thermistor or resistance RB. R4 can be 150 kQ if R9 is not used. If power is removed,
