In this type, the addition of a capacitor to the primary circuit makes it possible for an autotransformer ballast to provide a high power factor. The high power factor autotransformer is usually designed with an extra capacitor winding within its copper windings in order to provide a more economical and efficient system. The ballast’s power factor can be increased to about 90% by combining the extended windings with the capacitor. The input current is reduced, as in the high power factor reactor. Lamp performance and regulation are also the same as a reactor ballast at +/- 5%.

A ballast is an integral component of most modern lighting systems. It is primarily designed to perform three critical tasks: Deliver the proper voltage to start or ignite the lamp(s), Regulate the electric current flowing through the lamp(s), and Compensate for variations in line voltage. The ballast must correspond exactly to the requirements of the lamp it is designed to operate in order to ensure optimal performance.
