基于ARM的高频开关电源数字控制系统设计

Design of the Digital Control System of the High Frequency Switching Power Supply with ARM

随着新型功率器件的日趋成熟,更灵活可靠的数字控制是开关电源的发展方向。基于此,采用了先进精简指令集运算机(ARM)处理器来实现脉宽调制(PWM)移相控制信号的输出,以实现软开关电源PWM反馈回路的数字控制。实验结果表明,设计能达到预期的性能要求。

Abstract： With the more mature new power devices, more flexible and reliable digital control has become the trend of the switching power supply. This paper achieves the output of PWM Phase-shifted control with the ARM CPU. The experimental result is consistent with the theoretical feedback loop of the digital control of the soft-switching power supply rapid responsibility, stable reliability, and so on. output. has the This indicates advantages of that the PWM flexible design,
