Linear High-voltage High-power Amplifier for Piezoelectric Actuators

Piezoelectric actuators are increasingly used in smart structures due to their reliability and performance characteristics. However these actuators present highly reactive impedances that make it difficult to design efficient drive amplifiers. This paper presents a high-voltage, high-power amplifier for driving piezoelectric actuators in smart structure systems. A linear amplifier concept has been realized using a combination of operational amplifiers and […]
