Power controller for supercapacitor

Abstract

A power controller, including a supercapacitor, a motor, a switching tube, an annunciator, an output resistor, a sampling resistor, a filter capacitor, a voltage-stabilizing circuit, a fly-wheel diode, and a switch. The supercapacitor, the motor, the switching tube and the sampling resistor are connected in series to form a main working circuit. The signal output end of the annunciator is connected to a trigger electrode of the switching tube via the output resistor. The sampling end of the annunciator is connected to the sampling resistor. The motor is connected in parallel to the fly-wheel diode. The sampling resistor is connected in parallel to the filter capacitor. The Vcc end of the annunciator is connected to the supercapacitor via the voltage-stabilizing circuit. The state control ends of the annunciator are connected to the GND or Vcc of the annunciator via the switch.
