Title: DRIVER FOR A HIGH VOLTAGE CAPACITIVE ACTUATOR
Abstract:
A driver for a circuit with a capacitive load, is disclosed, including a power converter to receive an input voltage and generate a clean folded waveform as an output. An unfolding stage referenced to the input voltage is configured to receive the clean folded waveform from the power converter and unfold the folded waveform into a full waveform. The driver includes a controller to control the driver. The converter may operate bi-directionally.
