Abstract

A phase cutting control dimmer arrangement adapted to minimise electro-magnetic interference noise including a gate drive with an electrical input path to the connected gates of back-to-back FETs or IGBTs including a first resistor, a second resistor and a capacitor. The capacitor is adapted such that when at a first instant a switching voltage to turn OFF the FETs or IGBTs is first applied to the connected gates the capacitor is enabled to provide a current through the first resistor that adds to a current flowing into the second resistor thereby increasing a total gate drive current into the connected gates of the FETs or IGBTs minimising a time delay between an application of the pulse-enabled signal to the connected gates of the FETs or IGBTs and the switching OFF of the FETs or IGBTs.
