ABSTRACT:
A soft-start circuit includes a power source, a switch, a capacitor and a regeneration brake circuit. The regeneration brake circuit absorbs a return current. The regeneration brake circuit includes a resistor, a diode and a transistor. The resistor is connected between two poles of the power source via the transistor. The diode is connected between the resistor and the positive pole of the power source via the switch. The capacitor is connected between the negative pole of the diode and the transistor. The switch is connected between the negative pole of the diode and resistor. When the switch turns off, the power charges the capacitor via the resistor and the diode of the regeneration brake circuit. When the switch turns on, the return current turns the transistor on, and the resistor absorbs the return current.
