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 ...

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 ...

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 ...

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 ...

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 ...

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.
