摘要： An electrical extension cord includes a leakage current detector interrupter (LCDI) with reset lockout that can interrupt the power being supplied a line side of the cord to a corded appliance or to household wiring when a leakage current is detected flowing from any of the wires in the load side of the cord to a shield within the cord. The LCDI may be enclosed in a housing on a plug end of the cord that includes the plug for connection to the line.

摘要： A compact module with a pair of transformers and a double pole single throw relay (DPST) mounted onto a housing to create a self contained assembly for installation in a ground fault circuit interrupter (GFCI) as a unit. The first transformer has a core and is electrically coupled to a first set of terminals for connection to a printed circuit board (PCB). The second transformer is located adjacent to and magnetically coupled to the core of the first transformer and is electrically coupled to a second set of terminals for connection to the PCB. The DPST relay has a pair of stationary contacts and a pair of movable contacts for selectively connecting line phase and neutral conductive paths to a load.

摘要： A solid state motor speed control is described that is capable of controlling a motor so that it operates quietly, eliminating annoying buzzing noises that would otherwise be generated by the motor's windings. The invention provides for motor speed control with infinitely variable speed control settings. Rather than use triacs that generate RFI noise and cause motor windings to buzz due to their inherent avalanche switching, the invention utilizes power FETs or IGBTs to provide the switching function to control power delivery to the motor load. The power switches are controlled by an oscillator that generates a pulse train with a duty cycle controllable by the user. A filter shapes this signal into a trapezoidal control signal that drives the gate input of the power FET or IGBT switch. A kick start circuit turns the motor on initially for two to three seconds to overcome the inertia of the motor and its load. A zero crossing detector prevents the motor from being turned on except at a zero crossing of the AC source to further reduce noise.
