• DC distribution system
• limitation of deliverable power
• voltage instability

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, P-lim, 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 P-lim 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 P-lim. Measurements of the voltage waveform at the load terminals successfully support P-lim derived from the theoretical calculation.
