英文摘要：

For the control applications of piezoelectric objective lens actuator used in digital confocal microscopy system, a unipolar output voltage power supply is designed by using the LTC6090 opera-tional amplifiers as the core, and applying error amplifier circuits combined with bridge circuits. The given experiments show that the power supply has not only the characteristics of relatively simple structure and low cost, but also good linearity, low static ripple and good square wave response, so it can meet the driving requirements of piezoelectric objective lens actuator used in the presented system.
