Abstract
A solenoid driver circuit for a circuit breaker is provided. The circuit breaker includes a control circuit, a solenoid and secondary contacts and is structured to be coupled between a power source and a load. The solenoid driver circuit includes a first switch coupled to a solenoid and a first resistor structured to sense solenoid current; a second switch coupled to a second resistor, the second switch structured to be turned on based on a switch drive signal from the control circuit; one pulse width modulation (PWM) current controller coupled to the control circuit, the first switch, the second switch and the first resistor, the one PWM current controller structured to adjust the solenoid current and drive the solenoid to open or close the secondary contacts using a plurality of peak solenoid current limits including a first peak solenoid current limit and a second peak solenoid current limit.
