| 摘 要： | 研究了开关线性复合功率变换技术,提出一种复合型精密电流源的方案。该电源结合了高频开关电源和推挽线性功放电路的优点,输出波形好,效率高、体积小。同时采用三态自适应滞环电流控制方式,有效地减小了输出电流的脉动纹波。根据设计的方案制作了一台样机,实验结果表明该电流源纹波系数小、效率高,验证了方案的可行性。

| Abstract: | Switch-linearity hybrid power conversion was researched and a hybrid precise current source was proposed based on the technology.The current source combined the advantages of switching power module and linear power module.It had excellent waveform,high efficiency and small volume.A novel self-adaptive three-state hysteretic control strategy was also used to reduce the ripple of the output current.Then a model machine was produced according to the design scheme.The result showed that this current source had ... |
