| Abstract: | To meet the requirement of phase controlled for S-type linear piezoelectric motor,a new type of driving power was designed.for The design of a signal generator based on direct digital synthesizer（DDS） and programmable system on chip（PSOC3）,providing 3-phase sin wave voltage signal with 120° phase difference was proposed.The CD4051 and LM358 was used as the main component to design the PGA circuit.A linera power amplifier circuit was designed,and the problem of quick-discharge for the piezoelectric stack was solved.The experimental results demonstrate that the driving power is reliable for the s-type linear piezoelectric motor with long-time stability. |
