Title:
METHOD AND APPARATUS FOR POWER OUTPUT CONTROL AND CORRECTION
Document Type and Number:
WIPO Patent Application WO1998057244
Kind Code:
A3
Abstract:
A power factor correction system includes a sensing device in communication with a power supply to measure the line voltage on conventional service lines and detect any voltage fluxuations. A temperature controller receives power from the service lines and supplies an output voltage, based on the line voltage input, to one or more resistive loads, such as heater members. The heater members in turn are used to keep material in a molding device in a molten condition and within a certain temperature range. Fluctuations in the line voltage are detected by the sensing device which prevents corresponding changes in the voltage supplied to the resistive loads from the temperature controller.
