Piezoceramic actuators have been applied to high-precision control devices requiring high-frequency motion, such as nano-positioning systems, high-speed micro-mechanical systems, scanning probe microscopes, vibration control systems, and the like. The piezoelectric ceramic actuator is mainly based on the inverse piezoelectric effect, and the piezoelectric ceramic is deformed under the action of an electric field, so that execution components such as a probe and the like are driven to generate micro-displacement.
The traditional piezoelectric ceramic driver power supply mainly has two forms, namely a switch type driving power supply based on a direct current conversion principle, which has small volume, small power loss and high efficiency, but has larger high-frequency interference, larger power output ripple and narrower frequency response range.

Therefore, the traditional piezoelectric ceramic driving power supply is difficult to simultaneously meet the requirements of large output voltage range, high linearity, high efficiency and the like.
