The control circuit in Figure 1a allows you to manually adjust the power delivered to a load. By changing the setting of potentiometer R 3, you change the phase angle at which the thyristor (Q 3) ...

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...

This SCR phase control works much like the common TRIAC dimmer, but has numerous advantages including increased current capability, robustness and absence of minimum voltage “snap-on.” A complementary ...

The transformation of the power landscape involves more than just generation. The distribution of electricity is being changed as well, with technology designed to make electrical systems safer, more ...

This week the world’s first and only digital circuit breaker was certified for commercial use. The technology, invented by Atom Power, has been listed by Underwriters Laboratories (UL), the global ...

Racking in or out a power circuit breaker is simple, right? Although this task sounds pretty straightforward in theory, that’s not always the case. In fact, during years of field work related to ...

The quest for higher power and greater efficiency in all power supplies never ends, especially when it comes to all heavy-duty converters. Some examples are power supplies used in data centers, ...

Selecting the right solution to optimize the distribution of power to the connected loads is imperative for maximum system uptime. Switches, breakers, remote signals across Ethernet and automated ...

Tighter integration The cryogenic quantum control platform developed by David Reilly at the University of Sydney. (Courtesy: Fiona Wolf/University of Sydney) Researchers in Australia say that they ...

If you grew up with adults telling you to unplug appliances to save electricity, it turns out, they weren't being dramatic — those appliances can continue to drain energy, even if you power them off.
