Front end topology and some tips to design a mixed bridge circuit that effectively protects the design from an overvoltage. A robust solution using a new SCR generation and front end topologies that ...

ON Semiconductor introduced the NCP1901, an integrated circuit that combines both a power factor correction (PFC) controller and a resonant half-bridge controller in a single package. The high level ...

The FAN7529 is an active power factor correction (PFC) controller for the boost PFC application that operates in the critical conduction mode (CRM). The critical conduction mode boost power factor ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Most discussions on manufacturing energy efficiency focus on identifying easy-to-find-and-fix energy wasters such as compressed air leaks, inefficient lighting, equipment that is always left on when ...
