Abstract:
A two-wire load control device (such as, a dimmer switch) for controlling power delivered from an AC power source to an electrical load (such as, a high-efficiency lighting load) includes a thyristor coupled between the source and the load, a first circuit coupled between a first main terminal and a gate terminal of the thyristor to conduct current through the gate terminal, a second circuit coupled between the first main terminal and a second main terminal of the thyristor to conduct current through the load when the thyristor is non-conductive, and a control circuit configured to individually control the first and second circuits. The control circuit renders the first circuit conductive to conduct a pulse of current through the gate terminal to render the thyristor conductive at a firing time, and allows the first circuit to conduct at least one other pulse of current through the gate terminal after the firing time.
