Abstract
According to the requirement of the long range detection of the circumferential detection system of the laser fuze, a hybrid modulated pulsed laser driving power supplying for APD avalanche photodiode is designed. The working principle of the laser circumferential detection system is analyzed, and the APD is selected as the photoelectric detector according to the measurement equation of the circumferential detection system. According to the different kinds of APD requirements for high voltage power supply, the principle of boost converter is analyzed. By using PWM and PFM hybrid modulation type power supply technology, PWM modulation is applied in low rising voltage. When the voltage is required to achieve more than 100V, PFM mode boost is chosen. Simulation of the output voltages which are 85V and 200V of the two modes respectively is made. The PCB circuit board is processed to verify the experiment. The experimental results show that the hybrid modulation pulse laser drive power supply can meet the requirements of all kinds of APD power supply. The circuit board can be used in the detection of laser fuze with different target distance, and has wide application prospect.
