Abstract
A sustained-arc control system is constituted with a capacitance which is placed between a gap on a solar battery array, working to control or inhibit the sustained arc. A solar battery array has a plurality of solar cells to provide a power source onboard an artificial satellite. A plurality of series circuits each of which composed of the solar cells connected in series is connected in parallel. The sustained-arc control system on the solar battery array is constituted with a capacitance lying between a positive line and a negative line to be charged with a voltage oscillation arising from the sustained arc. Electrostatic capacity of the capacitance is in a range of from at least 33 nF to 10 μF.

1-5. (canceled)
A system for controlling a sustained arc on a solar battery array, comprising;
- a plurality of series circuits having solar cells connected in series with one another, and a power source connected through a positive line and a negative line to a positive terminal and a negative terminal of a load carried on an artificial satellite;
- wherein a capacitance to control the sustained arc is placed between the positive line and the negative line of the series circuit or between preselected series circuits;
- and
- wherein the capacitance is charged with a voltage oscillation arising from the sustained arc to prevent a short circuiting between the solar cells, thereby preserving a potential difference between the solar cells, getting a current fed to the sustained arc gone away or disappeared, shortening duration of the sustained arc, and eventually leading the sustained arc to extinction.
A system for controlling a sustained arc on a solar battery array as set forth in claim 3, wherein the electrostatic capacity of the capacitance is in a range of from at least 33 nF to 10 μF.
