Toroidal transformers typically consist of copper wire wrapped around a cylindrical core. This design prevents the magnetic flux that occurs within the coil from leaking

Pulse transformers interface a pulse forming network (PFN) and a load. They match the impedance of the load to the PFN in order to maximize power-transfer efficiency

Lamps are light sources that emit incoherent light for illumination. There are many different types of products. Examples include fluorescent lamps, halogen lamps, heat lamps, incandescent lamps, LED lamps, projection lamps, spectral lamps, and stage lamps. Specialized and proprietary lamps are also available.

Impedance matching networks are electrical circuits which, when connected between two networks, match the output impedance of the source (the first network) to the input impedance of the load (the receiving or second network). The purpose of matching these two impedances is to minimize wave reflection and/or to maximize the transfer of power between the system and the load.

Three phase uninterruptible power supplies (UPS) are devices that operate in conjunction with existing electrical systems to provide power conditioning, back-up protection and distribution for electronic equipment loads.

Fluorescent lamps are high-efficiency lamps that use electrical discharge through low-pressure mercury vapor to produce ultraviolet (UV) energy, which is then transformed into visible light

IC switching voltage regulators are integrated circuits (ICs) that store energy in an inductor, transformer, or capacitor and then use this storage device to transfer energy from the input to the output in discrete packets over a low-resistance switch

High voltage power supplies use linear technology to provide one or more DC outputs at voltage levels of hundreds or thousands of volts.

Electric and gas utilities supply electric power and/or natural gas or connect lines to industrial, commercial, and residential customers.

DC-DC converter chips provide a regulated DC voltage output from a different, unregulated input voltage. 

Power meters and wattmeters are used for high-accuracy measurements of power over a wide-frequency bandwidth, and from both AC and DC circuits.

Single phase uninterruptible power supplies (UPS) sit between an AC outlet (i.e., a wall outlet or power strip) and an electronic device (e.g., computer, server, or phone equipment) to provide power conditioning, back-up protection and distribution for electronic equipment loads.

CCFL controllers provide control functions for direct drive inverters used to operate cold cathode fluorescent lamps (CCFL). CCFLs are used for back or edge lighting of liquid crystal flat panel displays (LCFPD) .

IC voltage regulators are three-terminal devices that provide a constant DC output voltage that is independent of the input voltage, output load current, and temperature. IC voltage regulators are used in power supplies that hold their output voltage constant over a wide range of load variations.

Power transformers convert power-level voltages from one level or phase configuration to another.  They can include features for electrical isolation, power distribution, and control and instrumentation applications
