电机控制，精确发送的脉冲微调天线的共振点的火车上的直流电压由PWM电路。
The motor is controlled by a PWM circuit that precisely sends DC voltage on a train of pulses for fine tuning the antenna to the resonance point.
如果工频放电电压值超出范围，可对间隙进行微调。
If the working-frequency discharging voltage value exceed normal range, can faintly adjust the discharge gap.
设计了基准电压源和电压微调电路，为adc提供参考电压和电流，而且能进行一定范围内的微调。
Design a bandgap voltage reference circuit and a voltage-modifying circuit to provide precise voltage and current reference for the referred ADC.
