Abstract

A new multiple DC-inputs direct electric-power converter (D-EPC) was proposed. It can be applied to motor-drive systems with two direct-current (DC) power sources. The D-EPC can charge a DC power source with motoring by another DC power source. This charging is controlled by the voltage command multiplied by a power distribution ratio of more than 1.0 for the DC power source supplying power to the motor and another DC power source. If charging power is required in the condition of phase voltage saturation, the phase voltage command calculated using the power distribution ratio of more than 1.0 cannot be increased to more than the phase voltage limit. This paper proposes a new charging control for D-EPCs by controlling the switches on the free-wheel current path. The distribution ratio of this proposed control does not exceed 1.0. The simulation results showed that one DC power source can be charged with motoring by another DC power source using the proposed charging control.

一种新型直流电源串联D-EPC充电控制方法

提出了一种新型的多路直流直接电力变换器(D-EPC)。它可以应用于具有两个直流(DC)电源的电机驱动系统。D-EPC可以通过另一个直流电源的驱动为直流电源充电。该充电由电压命令乘以向电机供电的直流电源和另一直流电源的大于1.0的功率分配比来控制。如果在相电压饱和的情况下需要充电功率，则用大于1.0的功率分配比计算的相电压命令不能增加到大于相电压限值。本文提出了一种通过控制自由轮电流路径上的开关来控制d - epc充电的新方法。该控制的分布比不超过1.0。仿真结果表明，利用所提出的充电控制方法，一个直流电源可以被另一个直流电源充电。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
