Latest Patents

Pendergrass holds a patent for a "Direct Current Voltage Power Backup System." This invention provides a reserve power system for commercial AC loads, supplying DC power when the primary power source fails. The system is designed to maintain the operation of the load in a normal fashion by utilizing a DC power source. The patent outlines a mechanism where AC power is supplied to a primary winding of a transformer, which also features a secondary winding. A cable connects the secondary winding to the load powered by commercial AC voltage. Additionally, a battery DC voltage source and charger are integrated to maintain the reserve power's integrity. A voltage monitoring circuit detects primary power failures and activates switching circuitry to connect the DC voltage source directly to the load, allowing for temporary power without adversely affecting the power cabling.
