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.
Claims10
A direct current (DC) deicing control system comprising:
- a direct current (DC) power source;
- and
- a periodic deicing waveform generator electrically connected to the DC power source, the periodic deicing waveform generator outputting 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 defining arc extinguishing events reducing arc formation in the DC deicing control system.
A direct current (DC) deicing system comprising:
- at least one deicing mat;
- and
- a direct current (DC) deicing control system operably coupled to the deicing mat, the DC deicing control system including a DC power source, and a periodic deicing waveform generator, the periodic deicing waveform generator outputting a switched DC voltage having a periodic electrical current waveform to the at least one deicing mat, the periodic electrical current waveform including periods of zero voltage and periods of non-zero voltage, the periods of zero voltage defining arc extinguishing events reducing arc formation in the DC deicing control system.
