摘要： 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.

摘要： A phase cutting controlled dimmer arrangement with over-current protection including load control for back-to-back FETs or IGBTs with connected gates. There is a current sensing resistor that provides a first and second voltage. A first transistor has an electrical pathway to the second voltage and a second transistor has an electrical pathway to the first voltage such that when the second or first voltages exceeds a threshold voltage, this is commensurate with an over- current event of the back-to-back FETs or IGBTs, triggering the first or second transistor into conduction wherein conduction of the first or second transistors provides a means to turn OFF the back-to-back FETs or IGBTs thereby withdrawing power to the load.

摘要： A method for controlling dimming of a dimmer arrangement to minimise effects of a ripple injection signal upon an AC mains supply input wave signal received by the dimer arrangement comprising: filtering a ripple injection signal from an AC mains supply input wave signal having said ripple injection signal superimposed thereon; inverting the filtered ripple injection signal; combining the inverted filtered ripple injection signal with the AC mains supply input wave signal having said ripple injection signal superimposed thereon to eliminate the ripple injection signal from the AC mains supply input wave signal to provide an AC mains supply wave signal from which a true zero crossing detection signal is derivable; wherein an input of the derived true zero crossing detection signal to a gate drive arrangement of the dimmer arrangement generates a timing reference signal to control an OFF or ON period for a load control arrangement of the dimmer arrangement, wherein said load control arrangement is adapted to turn OFF or ON the AC mains supply input wave signal having the ripple injection signal superimposed thereon to a lamp under the control of the dimmer arrangement for an ON or OFF period determined by the timing reference signal.

摘要： A method for controlling dimming of a two-wire trailing edge dimmer arrangement to minimise the effects of ripple injection or superimposing of supply authority ripple control signals upon AC voltage mains supply received by the two-wire trailing edge dimmer arrangement when controlling luminosity to a load under the control. The method includes the step of generating a stable timing reference signal to control an OFF period for a load control arrangement, said load control arrangement adapted to turn off electrical power to a load under control of a two-wire trailing edge dimmer arrangement at a trailing edge of an AC mains supply input wave whereby initialisation and/or timing at which said stable timing reference signal is generatable is variable by a switch detection level of a comparator monitoring amplitude of a scaled, low pass filtered, replica of an active terminal and a load terminal voltages of said two-wire trailing edge dimmer arrangement.
