| Abstract: | A PZT power supply with high accuracy and low drift is developed,which include digital tracking signal generator,composite amplifier and phase compensation circuits,etc.This composite amplifier uses a low voltage amplifier OP07 to control accuracy and drift,and the PA04 acts as voltage and current booster which are selected to diver piezotransducers.Furthermore,the stability of the composite amplifier are analyzed in detail,and optimum heatsinking are considered to improve the thermal resistance rating of heatsinks.The simulating results show this design is reasonable and effective. |
