摘要
提出一种复合型精密电流源的设计方案,该方案结合了高频开关电源和推挽线性功放电路的优点,具有波形好、效率高、体积小等优点。同时采用DSP作为控制核心,控制系统精确可靠,可以实现数字化控制。实验结果表明波形质量好,谐波失真度小,验证了方案的有效性。
A strategy of hybrid precise current source was proposed in this paper, which combined the advantages of switching power and linear power with excellent waveform, high efficiency and small volume. DSP was used as the core of control system, so the system was precisely, reliably and digitally controlled. The result of experiment shows that the current source has good waveform quality and low THD, which proves the effectiveness of the strategy.
