What is Ramp and Pedestal Control Circuit about?
This patent describes a ramp and pedestal phase control circuit for controlling electrical energy supplied from an alternating current source to a load. The circuit uses a controllable switching device and bilateral threshold means to enable the switching device when the voltage across the threshold means exceeds a predetermined value. A first circuit rapidly increases the voltage across the threshold means to a value less than the predetermined value, and a second circuit more slowly further increases the
