零电压调整率和零内阻前馈控制式线性稳压电源

ZERO-VOLTAQE-REGULATION AND ZERO-INTERNAL RESISTANCE FORWARD-FEED LINEAR REGULATED POWER SUPPLY

分析了稳压电源中直流输入电压扰动和负载电流扰动对直流输出电压的影响;根据前馈控制理论给出了扰动的最佳补偿条件,这些条件适用于所有线性稳压电路的设计。以一个射极跟随式串联型稳压电源为例,给出了这种补偿式稳压电路的设计方法和公式。测试表明,这种补偿式稳压电路的S和R_0优于反馈式稳压电路。

Influences of input voltage and load current fluctuations on d.c. output voltage in a regulated power supply are analysed. Based on the theory of forward feed control the optimum compensation conditions are given in this paper. These conditions can be used in the design of different types of linear regulated circuits, and the design method and formulations are given with an example of emittar following series regulator. The test results show that the S and R0 of compensation type of regulated circuits are better than those of feedback regulated circuits.
