Abstract
A direct current (DC) deicing control system including a direct current (DC) power source, and a periodic deicing waveform generator electrically connected to the DC power source. The periodic deicing waveform generator outputs a switched DC voltage having a periodic electrical current waveform including periods of zero voltage and periods of non-zero voltage. The periods of zero voltage define arc extinguishing events reducing arc formation in the DC deicing control system.
