摘要
介绍了一种适用于有源光电式互感器的悬浮式直流电源的设计原理。通过选择合适的工作点、采用增加补偿线圈改善原方激磁电流对电源变压器二次侧感应电压影响的方法,研制出一种适用于传感器高压回路信号处理的电源样机。大量实验表明:该电源具有工作动态范围宽、输出功率大的特点,完全满足有源光电式互感器高压侧对信号处理工作电源的要求。
The principle of a floating type DC power supply is introduced,which is used in the active photoelectric transducer for signal processing at high voltage side. By means of choosing suitable working point and adding a compensation coil to weaken the influence of primary current on the induced voltage of the power transformer,a prototype device has been developed. Experiments show that it has wide dynamic working range and large power output. It can completely satisfy the requirements of active photoelectric transducer for signal processing at high voltage side.
