ABSTRACT:
A method for reducing the harmonics created by rapid-start fluorescent lamp stabilizer balance systems is accomplished by increasing the number of turns of the secondary winding of the transformer so as to decrease the secondary current to approximately 40 to 90 percent of the rated lamp current. This method increases the impedance and reduces the secondary current between 40 and 90 percent of the rated lamp current. While the absolute value of the illuminous intensity is lowered by the reduction in the secondary current, the lamp maintains a uniform brightness of illumination. This method decreases the distortion in the primary wave form which decreases the distortion effect on sensitive electronic systems which may be connected to the same electrical power source or may be in the area near the stabilizer.
