These days, homeowners are clamoring for pendants that hang from the ceiling, moody undercabinet lighting, recessed lighting and outdoor path lights that illuminate the edge of the front walk. Of ...

The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

Commonwealth Edison delivers power to 4 million customers in northern Illinois, U.S., including the entire city of Chicago. More than 90% of these customers have advanced metering infrastructure (AMI) ...

Rosslyn, Va.-based National Electrical Manufacturers Association (NEMA) recently announced the initiation of the NEMA Premium Efficiency Transformer program, which will help utilities, commercial ...

The circuit diagram was designed to create a power supply without utilizing any transformer circuit. This circuit illustrates the advantages as well as the safety precautions to keep in mind. Power ...

Each of the three basic types of light sources — incandescent, fluorescent, and HID — has its own particular applications and advantages. The proper selection of a lamp type will ultimately depend on ...

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

There are a number of potential solutions to the classic EMC problem of providing immunity from mains borne interference, especially in the form of surges, sags, brownouts, lightning strikes and noise ...

The technology promises to replace several parts of the grid with one device that’s both controllable and updatable.
