摘要：

The self-starting function with low power consumption of the wireless charging system is designed and implemented. The MSP430F5529 is used to carry on AD sampling to the circuit in order to realize the self-starting function, which effectively reduces the power consumption of the control system. The super capacitors are used to store electrical energy, which controls the DC-DC conversion through the TPS63020 chip. The ripple of the output voltage is less than 76 mV, which effectively reduces the power consumption of DC-DC conversion circuit. The experimental results show that the power utilization rate of wireless charging reaches more than 85%, which ensures the stability of the output voltage and reduces the power consumption of the system.
