摘要： A driver circuit drives a pulse width modulation (PWM) controller. The driver circuit includes an enabling circuit, a power supply input control circuit, a stabilizing circuit, and a discharge circuit. The stabilizing circuit is electrically connected to the PWM controller. The power supply input control circuit is electrically connected between the enabling circuit and the stabilizing circuit. The discharge circuit is electrically connected between the stabilizing circuit and the ground. In response to the driver circuit working in normal operation, the enabling circuit enables the power supply input control circuit to output a working voltage to the stabilizing circuit, and in response to the process of the driver circuit restarting, the enabling circuit enables the power supply input to stop outputting power supply to the stabilizing circuit. The discharge circuit leads a residual voltage of the stabilizing circuit to the ground, during the process of the driver circuit being restarted.

摘要： A measurement circuit includes a switch unit with a number of keys selectively pressed to output different resistance regulating signals. A resistance setting circuit receives the resistance regulating signals and connects different resistances to a voltage circuit and a current circuit. The voltage circuit outputs different voltages. The current voltage receives a voltage from the voltage circuit and outputs a current to a capacitor. A detecting circuit measures a temperature of the capacitor and outputs the temperature to the resistance setting circuit. The resistance setting circuit compares the received temperature with a preset temperature. If the received temperature is equal to or greater than the preset temperature, the resistance setting circuit outputs short-circuit information of the capacitor. If the received temperature is less than the preset temperature, the resistance setting circuit outputs normal information of the capacitor. A display unit displays the information of the capacitor.
