Cycle Charge Standby Power System

US Patent:
4362951, Dec 7, 1982
Filed:
Dec 10, 1980
Appl. No.:
6/215005
Inventors:
Charles S. Turner - Dallas TX
Donald J. McNeal - Garland TX
Donald G. Cheshier - Garland TX
James C. Gray - Garland TX
Assignee:
Control Technology - Dallas TX
International Classification:
H02J 906
H02J 704
US Classification:
307 66
Abstract:
Disclosed is a standby power supply system appropriate to supply a set of signal amplifiers within a cable television network. The standby power supply normally operates off of utility company power and alternatively operates from a battery power supply during power failures. Circuitry is disclosed to use battery power during failure mode operation to generate a pulse width modulated alternating current of substantially constant true rms voltage and of substantially constant frequency. Circuitry is also disclosed to cycle charge the battery supply to a desired voltage and then stop the charging cycle and begin timing normal mode operation until another charging cycle. Further, isolating circuitry is disclosed to remove much of the load on the battery supply during normal mode operation. Various safety provisions including soft start provisions, a high current cut off, a low voltage cut off, and protection for the amplification stages is included. Finally, various types of status monitoring equipment are disclosed.
