Non-insulated power supplies are often required when a power semiconductor, which has to be controlled using this supply, has its drive reference connected to the mains (line or neutral terminal).

One of the biggest challenges for new, energy-efficient CFL and LED-based lights that will replace incandescents is working with existing triac-based dimmer switches. Triac dimmers vary widely in both ...

Electric vehicles promise advantages for the environment in terms of reducing local emissions along with advantages to the hip-pocket in respect to running costs. Unfortunately at this stage of the ...

Fairchild Semiconductor introduced the FL7730 single-stage primary side regulation (PSR) controller with power factor correction (PFC) for use with triac and analog dimming compatibility. Fairchild ...

Diacs and triacs often are used for line-voltage control. They also are getting additional interest as part of Internet- and cell-phone-controlled power-line switches such as the Belkin WeMo Home ...

Power-control modules are circuits comprising devices such as silicon-controlled rectifiers, triacs, power transistors, and power rectifier diodes. Power-control modules are circuits comprising ...

IXYS subsidiary Clare has made available CPC1998, a 5Arms AC solid state switch utilizing dual optically isolated power SCRs, as an integrated alternative to discrete optocoupler and Triac circuits.
