    • Abstract
  • This paper introduces a high precision high-voltage feedback control circuit.The transmitting circuit turns the real-time voltage into serial digital signals to modulate the light of the semiconductor laser.After passing the high-voltage insulating barrier,the light is received by receiving circuit.Through photodiode and 74AHC inverter,the serial digital signals are obtained and sent to the microcontroller to form a closed-loop control.
