摘　　要：介绍了一种基于DSP控制的半导体脉冲激光电源,主电源电路采用半桥逆变的电压反馈式谐振变换电路,控制和保护电路以TI公司的TMS320F2812数字信号处理器为核心,外加外围驱动电路和硬件保护电路,DSP准确程控电源输出信号的频率、脉宽、脉冲电流幅度和电压大小。This thesis introduces a design of a new diode laser pulse power supply. A voltage feedback and half bridge convert resonance transform circuit is used in the main power circuit. The new digital signal processor of TI, TMS320F2812 , which is the core part of the power source, some peripherals, and the hardware protection circuit make up the control and protection part. The DSP can exactly control the frequency, pulse width, the amplitude of the current and the voltage of the output.
