Abstract :
The design of a new driver based on Programmable System on Chip (PSOC3)is proposed. According to the requirements of piezoelectric linear motor,a signal generator providing 4-phase sin wave voltage signal with 90° phase difference is designed. The embedded chip is used as the main processor, and the DMA data transmission technique is adopted to increase the efficiency of the main processor. An operation buffer and linear power amplifier circuit is designed and the amplitude-frequency characteristics are analyzed. The experimental and analytical results demonstrate that the driver is reliable for the piezoelectric linear motor with long-time stability and the alternation operation of the promoter.
