摘要:
为实现双驱动足压电作动器的作动,设计相应的驱动电源。该压电驱动电源采用 3 通道信号发生器,产生 3 路相位差为 90° 的方波信号,再经过 3 通道线性放大电路,其由 OPA2277UK 和 PA79DK 构成的 2 级线性放大电路,输出 3 路大功率偏置信号驱动电机运行。同时,针对容性负载对电路的影响进行分析并且采用隔离电阻、反馈电容和对称相位补偿方案,防止驱动电源自激振荡。实验结果表明,该驱动电源可以输出不同的电压控制信号,具有良好的稳定性和可靠性,能够满足电机的应用要求。
Abstract:
In order to realize the operation of the dual-drive foot piezoelectric actuator , a corresponding drive power supply is designed.The piezoelectric drive power supply uses a three-channel signal generator to generate three square wave signals with a phase difference of 90° , and then passes through a three-channel linear amplifier circuit consisting of OPA2277UK and PA79DK as a two-stage linear amplifier circuit to output three high-power bias signals to drive the motor operation.Meanwhile , the impact of capacitive loads on the circuit is analyzed and an isolation resistor , feedback capacitor , and symmetric phase compensation scheme are used to prevent self-excited oscillations of the drive power supply.The experimental results show that the drive power supply can output different voltage control signals , has good stability and reliability , and can meet the application requirements of the motor.
