普通供电器与稳压式供电器特性差异初探

对两类供电器输出电源的特性进行初步的分析探讨,得出用普通万用表、数字式万用表和场强仪测量磁饱和稳压式供电器输出的近方波电压值时读数偏高约6%,建议乘以0.94来矫正;同时认为近方波电源通过放大器内电容输入式整流滤波电路后的直流电压比输入同电压的正弦波电源低,放大器中应选用变压比适当的变压器,应用放大器时要插准电压选择档位.

Difference Between Classical Power Supplier and Regulated Voltage Power Supplier

The analysis of the two classes of power supplier reveals that the reading of approximate square wave voltage of regulated voltage magnetic saturated power supplier with ordinary multimeter, digital multimeter and strong level meter is higher than true value by about 6%, and should be rectified by a 0.94 multiplier. At the same time, output volts D.C. of rectifier of capacitor-input filer in an amplifier with input of approximate square wave supplier is lower than that of sine wave supplier so the transformation-ratio of the transformer in amplifiers should be properly designed, and the right selector should be used to provide accurate voltage.
