Abstract
This paper describes High Voltage Driver (HVD) development for Piezoelectric Fast Steering Mirror (PFSM). Piezoelectric actuator's highly capacitive nature and its influence on high voltage driver are discussed. Since the PFSM tends toward higher speed and larger angle, a multi-paralleling power booster output stage linear high voltage amplifier is described that can output significantly higher current than single output stage linear power amplifier. Test results are presented for a fast high voltage driver that can drive a 300mm diameter PFSM (2.5μF piezoelectric actuator) at 100Hz 1000Vpp, also at 5000Hz 20Vpp.
