Latest Patents
Alfredo H Saab holds a patent for a power factor controller. This device is designed for motors and utilizes a bidirectional triode thyristor. The controller features a circuit that senses the voltage across the thyristor to determine the lag time of the current relative to the line voltage. It generates a signal voltage across an integrating capacitor that is inversely proportional to the current lag time. Additionally, a voltage ramp generator produces a ramp voltage that increases in slope as the lag time decreases. The combination of the signal voltage and ramp voltage is applied to a threshold detector, which triggers the thyristor when a predetermined threshold is reached. This innovative design minimizes power dissipation, size, and cost by employing only five integrated switches or gates and two individual transistors.
