摘要
1000V可调脉动直流电源将自耦调压器与升压变压器相结合设计。交流电源送入自耦调压器输入端,调压后送至升压电路。升压电路输出分别送至整流和取样电路,整流后为峰值100Hz脉动直流电压输出。取样电路将取样信号送至比较控制电路与设定电压值进行比较,再用比较结果控制伺服电机,以改变自耦调压器输出电压。并将电位器输出电压设定为0～1000V,当220V交流输入发生波动时,此电路可使输出稳定在设定值。
The 1000V adjustable pulsant direct current power source was designed based on the autotransformer and step-up transformer. The alternating current was sent to the input end of the autotransformer and pressure-rise circuit after adjusting voltage. The output of the pressure-rise circuit is sent to the commute and sample circuit, and 100Hz pulsant direct voltage output is gotten after being commuted. A sample signal is sent to the comparison and control circuit and compared with a voltage initialization. The comparison result controlled a servo electrometer. The output voltage would in 0-1000V with an adjustable resistance. When 200V AC was fluctuating, the circuit would keep the outout voltage at the initialization stably.
