Abstract
A bidirectional switch and dimmer for the control of power from an AC source to a load is described. The approach uses power MOSFETs in a bidirectional switch subcircuit configuration that includes a floating AC/DC power supply and a solid state double pole switch that alternates between connection of the AC source to the load and periodic connection of the AC source to the AC/DC power supply. The switch and dimmer circuit configuration allows insertion into an existing single-phase circuit using only two wires. The design allows for manufacturing the entire circuit on a single chip.
