Optocouplers Drove 20 Kilovolts at 500 Hertz
A feedback amplifier treats optocouplers as linear devices for electrostatic actuators.
Published Updated Story ID: mp-2026-09-25-017
Summary
A feedback amplifier treats optocouplers as linear devices for electrostatic actuators.
The prototype produced a 20-kilovolt peak-to-peak output with bandwidth up to 500 hertz at sub-milliamp current. The authors report lower distortion and higher bandwidth than equivalent pulse-width-modulated amplifiers with few components.
