Abstract

This paper proposes that a deliverable power through a low-voltage DC distribution system has an upper limitation. The upper limitation of the deliverable power, Plim, is explained on the basis of a voltage instability phenomenon occurring for the load with a voltage sensitivity below 1. From theoretical-calculation results, it is pointed out that Plim diminishes with augment in the distribution-line length. This phenomenon becomes more distinct for the higher distribution-line inductance per unit length. Connection of the capacitor to the receiving end of the distribution line is discussed as a method for rising Plim. Measurements of the voltage waveform at the load terminals successfully support Plim derived from the theoretical calculation.
