摘要:
无人机舵机控制系统广泛采用脉宽调制技术驱动电动舵机,其驱动电路为MOSFET构成的桥式逆变电路,工作中出现的门极驱动电压过冲现象,将影响整个舵控系统的传导EMI发射. 针对这一问题,首先分析了驱动电压过冲机理及对系统的EMI影响,然后提出了在驱动电路电源端加电容来抑制电压过冲. 最后,结合仿真和实验分析,证明了该措施抑制EMI噪声的有效性.
Abstract:
The actuator systems of UAV use PWM technology to drive electromechanical actuators,the drive circuit is to bridge inverter circuit composed of MOSFET. Drive voltage overshoot occurs during driving process,which can contribute conducted EMI emissions to the entire systems. To solve this problem,the mechanism of drive voltage overshoot and EMI to the actuator systems is analyzed firstly. Then,a method is proposed to add a capacitor at the power supply end of the driver circuit to suppress voltage overshoot. Finally,with the combination of simulations and an experiment,the effectiveness of the EMI suppression method is verified.
