Latest Patents

John C Berry holds a patent for a "Capacitive boost circuit for extending hold up time." This invention is designed to extend the operation of an electrical load after the interruption of its power source. The circuit includes bulk capacitors that are charged by the power source and regulated to a predetermined voltage near their peak-voltage rating. During normal operation, the bulk capacitors are isolated from the power source capacitors. When the power source is interrupted, these bulk capacitors provide the necessary hold-up for the load. This innovative circuit maximizes hold-up time for a given physical bulk capacitor size while ensuring a consistent hold-up time across a range of power source voltages.
