A low-voltage power supply converts alternating voltage into a direct voltage and is connected in parallel with the TTD. Gate current supplying circuitry is provided to supply current to the gate of the TTD, the gate current supplying circuitry powered by the low-voltage power supply and including a variable input device operable to vary a voltage waveform at the gate of the TTD in order to vary a voltage waveform provided at the second terminal. A method for controlling current through the load comprises controlling conductivity of the TTD by varying the voltage waveform at the gate of the TTD including, within a half-cycle of an alternating voltage being applied to the first terminal, applying a first voltage waveform at the gate, so as to place the TTD in a conducting state, followed by applying a second voltage waveform to maintain the TTD in the conducting state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control circuit for controlling current through a load using a phase-cut thyristor arrangement and method for controlling thereof","description":"A dimmer switch for an LED light source utilizes a thyristor-type device (“TTD”) having a first terminal, a second terminal, and a gate terminal.
