| 摘 要： | 提出了一种基于PSoC(可编程片上系统)的行波超声电机(TRUM)驱动器.电路包括幅值可调的DC/DC推挽升压电路和频率可调的DC/AC半桥逆变电路.升压电路将15 V直流电提升到250～400 V高压,并通过电压反馈稳定该电压.半桥电路将该高压输出两路相位相差90°的方波电压,用于直接驱动超声电机.通过检测电机孤极电压并调节电机驱动频率来稳定该电压,从而稳定电机转速.所有的控制功能都由一片PSoC芯片实现.通过对一直径45 mm的超声电机进行试验,证明了电机的驱动电压幅值和频率是可以独立调节的,为超声电机的控制提供了一个很好的方法.

| Abstract: | A novel driver for the traveling-wave ultrasonic motor (TRUM) based on PSoC is proposed.The driver is mainly composed of two parts:the first part is a push-pull DC/DC converter which enhances 15 V DC voltage to a high voltage of 250-400 V and can be adjusted and stabilized according to the status of the motor;the second is a half bridge DC/AC inverter composed by two bridge arms,its DC input is the output of the first part,and the outputs are two phases of high voltage square wave with 90 degree difference.... |
