Abstract

The invention provides a digital flyback laser gyroscope high-voltage power supply. The power supply comprises an MCU control module which is a digital chip, a conversion circuit and a comparator, wherein the conversion circuit is charged and discharged under the control of the MCU control module and generates high voltage, and a first feedback signal related to the input voltage of the conversion circuit is input to the MCU control module; the comparator compares the output voltage of the conversion circuit with a threshold value to generate a second feedback signal, and the second feedback signal is inputted to the MCU control module; the MCU control module controls charging and discharging of the conversion circuit according to the first feedback signal and the second feedback signal. The power supply is advantaged in that voltage generated by the power supply is high in stability, and the power supply is small in size.

Description

technical field [0001] The invention relates to a high-voltage power supply, and more specifically, to a digital flyback laser gyro high-voltage power supply. Background technique [0002] The laser gyro high-voltage power supply is a power supply with special functions. It needs to provide a high voltage for the gyro to discharge, and can provide a constant high voltage after the gyro is ignited, so as to maintain the normal operation of the gyro at a small current and the stable working voltage of the gyro. Generally between 2500V-3000V. [0003] Existing laser gyro high-voltage power supplies generate PWM signals through quasi-resonant control chips to control the charging and discharging of transformers. For example, the solution provided by the invention patent CN103630128 A uses the L6565 quasi-resonant control chip to generate PWM waves. The solution provided by the invention patent CN206891448 U is that when the starter control circuit is enabled, the quasi-resonan...
