摘要
当前研究的目的是证明AC/DC转换器可以在DC/DC转换器模式下工作,同时保持其功能和技术特性。本文采用实验方法,给出了电路原理图,从中得到了主要工作特性并进行了验证。能源效率系数的值是在400至600 V直流范围内电源电压值快速波动的情况下进行评估的。分配的任务被简化为在规定的工作范围内评估供电直流电压变换器的效率和功能特性。开发的AC/DC转换器旨在用于特定应用,例如在保加利亚Mini Maritsa Iztok EAD煤矿公司运营的EL-2工业机车中提供转换器电源的电池充电。EL2是一个强大的和直接的机器与Bo ' Bo '轴安排,旨在以中等速度拖重草稿。这些机车是为1.2或2.4千伏直流电压而制造的。
The aim of the current study is to demonstrate that an AC/DC converter may operate in DC/DC converter mode while maintaining its functional and technical characteristics. The paper employs an experimental method, presenting a circuit schematic from which the main operating characteristics were obtained and demonstrated. The value of the coefficient of energy efficiency was evaluated in the presence of quickly fluctuating supply voltage values in the range from 400 to 600 V DC. The assigned task is simplified to evaluating the efficiency and functional characteristics of the supplied DC voltage convertor within the specified operating range. The developed AC/DC converter is intended for use in specific applications, such as batteries charging that provide converters power supply in EL-2 industrial locomotives, operating in the coal mining company Mini Maritsa Iztok EAD, Bulgaria. EL2 is a robust and straightforward machine with the Bo‘Bo’ axle arrangement, designed to haul heavy drafts at a moderate speed. These locomotives were built for voltages 1.2 or 2.4 kV DC.
