| Abstract: | Power supply driven piezoelectric ceramics is the key component used in millimicron level worktable systems. This article puts forward a structure of power supply which uses multiple voltage supply as integrated control. Based on the structure we developed power supply driven piezoelectric ceramics controlled by micro controller based on D/A. The power supply is composed of tandem multiple dc voltage supply which is numerical control and may modulate,and it is used as key element of voltage stabilizer that integrated modeling LM 317. The designed supply has the features of high resolution capacity, quick responding speed, powerful driving, simple structure and debugging convenient of the designed power. It can apply to piezoelectricity ceramics actuator. |
