INTRODUCTION
It has often been a disadvantage with electronic ballasts that they have been unable to
be dimmed with a standard (phase cut) type of dimmer, particularly in the case of small
integral ballast-lamp combinations commonly used in the home to save energy. This is
due to the fact that, where there is no power factor correction, the ballast circuit input
consists of a rectification stage followed by a large storage capacitor connected to the
AC mains supply that provides the DC bus from which the high frequency half bridge
and output section is supplied. In such a system current is drawn from the mains only
near the peak of the mains voltage where the storage capacitor charges and not during
the remainder of the mains half-cycle.
Virtually all domestic and professional dimming systems are based on triacs. These
devices will conduct once they have been fired, only while current flows in excess of the
holding current of the device. These dimmers work very well with a resistive load such
as an ordinary Tungsten filament light bulb as the triac can be fired at any point during
the mains half-cycle and will continue to conduct until very close to the end of the half-
cycle as current is drawn continuously over this period. In this way the lamp current can
be adjusted from maximum to zero.
