摘要
针对探地雷达发射电路对于直流高压电源的需要,提出改进型稳压电路。本设计采用无工频变压器稳压电路,通过整流、滤波、稳压过程将220 V交流电变为稳定的直流电,实现电压在182 V～257 V范围内可调。与原电路相比,可以有效地提高效率,降低损耗,并且其输出电压的稳定性、电压的调整率均高于或等同于原线性稳压电路。即使与传统的脉冲高压电源比较,也具有重量轻、对系统干扰小的优势。该电路可应用于其它系统,具有较高的实用价值。
Given the need of the transmitter circuit of the ground penetrating radar for a power supply with direct current and high voltage, this paper presents an improved voltage stabilizing circuit. This design uses the non-power frequency transformer voltage-stabilizer circuit, translates alternating current to stable direct current through rectification, filtering and voltage stabilization and realizes the adjustability of the voltage between 182 V -- 257 V. It has the advantages over the existing circuit of higher efficiency, lower ullage, better stability and redressal of output voltage. It also has the advantages over the traditional pulse high voltage power supply of light weight and small disturbance to the system. This circuit can also be used in other systems and is therefore of great practical value.
