DIMMERS WITH AN IMPROVED GATE DRIVER CIRCUIT
This abstract first appeared for US patent application 18936301 titled 'DIMMERS WITH AN IMPROVED GATE DRIVER CIRCUIT
Original Abstract Submitted
A dimmer includes a TRIAC structured to conduct load current during an on phase and not conduct the load current during an off phase; a snubber circuit including a resistor and a capacitor electrically connected to the resistor at a node; and a bidirectional switch structured to transmit a gate current pulse to gate of the TRIAC to switch the TRIAC between the OFF phase and the ON phase, the bidirectional switch including a first MOSFET, a second MOSFET, a first resistor electrically connected to source of the first MOSFET and a second resistor electrically connected to source of the second MOSFET, drain of the first MOSFET being electrically connected to the node of the snubber circuit, and drain of the second MOSFET being electrically connected to the gate of the TRIAC.
