摘要：
A novel control circuit of electric charge extraction circuit and its method are presented. The circuit consists of control circuit and energy harvesting circuit. Control circuit is used to generate control signal EN to control switch on and off, so that the energy harvesting circuit part can work normally. The results show that under the condition of a gap of L = 16.5 mm between the two separation magnets and a motor speed of omega = 350 rad/s, the LED lighting with this circuit is about twice as large as that without this circuit.
