Generating device of high-voltage sine wave drive signal

The invention provides a generating device of a high-voltage sine wave drive signal. The generating device comprise a computer, a single-chip microcomputer, a field-programmable logic gate array, a digital frequency synthesizer, a transformer, a first low-pass filter, a bias voltage generator, a signal amplifying module, a bias power supply, a high-voltage power supply, a high-voltage amplifying module, a clamping circuit and a second low-pass filter. The amplitude-controllable sine wave signal output by the digital frequency synthesizer is amplified in the mode that the signal amplifying module and the high-voltage amplifying module are in two-stage cascade, and then the high-voltage sine wave signal is obtained through clamping by the bottom clamping circuit. In addition, the noise of the sine wave signal is eliminated through the first low-pass filter after being directly output by the digital frequency synthesizer and through the second low-pass filter after signal clamping. By the adoption of the generating device of the high-voltage sine wave drive signal, the generation method of the sine wave is simplified, the frame frequency of an electron multiplying charge coupled device CCD60 reaches over 1000 Hz, the frequency is increased by one time compared with the frequency of foreign cameras of the same type, and the generating device of the high-voltage sine wave drive signal is used for generating electron gain through high-frequency high-voltage gain drive of the charge coupled device.
