Abstract: A high-voltage (HV) waveform generator for driving an electrostatic actuator includes an HV source configured to generate a single HV rail at a predefined voltage with respect to a low potential, at least one switch circuit, and a controller. Each at least one switching circuit includes a first charge sub-circuit, a first discharge sub-circuit, a second charge sub-circuit, and a second discharge sub-circuit in a H-bridge formation to provide a first voltage output and a second voltage output. The controller includes software that generates variable current sources to control the first charge sub-circuit, the first discharge sub-circuit, the second charge sub-circuit, and the second discharge sub-circuit input to generate desired voltages at the first voltage output and the second voltage output based on feedback from a first voltage monitors for the first voltage output and a second voltage monitor for the second voltage output.
