Abstract
A circuit for controlling the initiation and operation of a phase control circuit employed in voltage regulation to a load such as dimming lights. The circuit uses a power semi-conductor which is triggered by a 'walk-in' circuit. The 'walk-in' circuit includes a regulator diode across a diode bridge which stabilizes the output of the load, such as a level of lighting.
