Diacs and triacs are often used for control of ac lines and are seeing increasing use in Internet-enabled line switches. However, the traditional approach of modeling them using bipolar transistors ...

Solid-state relays furnish effortless control. Conquer triacs for lowest installed cost with high efficiency. Zero-crossing-detector optotriacs alleviate control worries. As Italian tyre giant Pirelli ...

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 ...

Fig 1. This efficient pre-regulator for a dc power supply uses an optical feedback loop to minimize dissipation rather than the traditional optically isolated TRIAC drivers. Fig 2. The PSpice ...

Vishay Intertechnology is broadening its optoelectronics portfolio with the introduction of two integrated power phototriacs: the VO2223, which features an output current of 0.9A, and the VO2223A, ...

As Italian tire giant Pirelli's advertising reminds us, “Power is nothing without control.” But if your application is automotive, consumer, or industrial, embedded control is often worthless without ...
