摘　　要：针对不同应用领域对脉冲电源的性能和参数要求存在差别的问题,设计了一种基于DSP数字控制的可调高频脉冲电源。系统采用DSP作为信号源,产生3路相互间隔120°的PWM信号,通过驱动电路放大后驱动3路并联的全桥逆变电路,经高频变压器感应叠加后,在负载上输出幅值可调,频率为兆赫兹的高频脉冲。详细介绍了主电路、PWM分频电路、吸收缓冲电路以及变压器感应叠加的设计方法。最后对研制的脉冲电源进行测试,证明该电源已达到设计要求。For different application field of pulse power, there is a difference to performance and parameters of pulse power.The design of the high frequency pulse power supply is introduced based on DSP digital eontrol.DSP is used as signal source to generate three-way 120° spaced PWM signal.The pulse signal is amplified by driving circuit and then drives three paralleled full-bridge inverter circuit.The megahertz level and adjustable amplitude pulse is obtained on the load through the superposition of transformer induction.The main circuit, PWM frequency dividing circuit, ab- sorbing buffer circuit and the superposition of transformer induction are introduced.The experimental results show that the power supply has reached the designed requirements.
