Summary: | The utility model relates to an impulse voltage signal generation device for electrostatic force haptic display and belongs to the field of human-computer interaction and virtual reality. The impulse voltage signal generation device is composed of a waveform generation unit, a signal conditioning unit and a high-voltage amplification unit, wherein the waveform generation unit is composed of a phase accumulator composed of two adders and a phase register, a data memory and a D/A (digital to analog) converter, the signal conditioning unit is composed of a low-pass filter and a D/A controller, and the high-voltage amplification unit takes a high-voltage amplification chip PA90 as a core. The impulse voltage signal generation device is mainly used for an electrostatic force haptic display system, can generate various waveforms such as sine waves, amplitude-modulated waves and Gaussian waves, is simple in circuit and easy to realize, and has the advantages of high frequency, high amplitude, low power consumption, |
