In the figure is the simplest dual-way thyristor dimmer circuit, the feature of the dual-way thyristor is that whether the AC is in its positive or passive half circle, just add a proper trigger pulse or control circuit on its control pole, the thyristor will be passable, and the conducting time is relative to the pulse width or gate current. The brightness of bulb E can be changed by adjusting RP.
