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 ...

This post sponsored by Texas Instruments. UCC28019A is an 8-pin active Power Factor Correction (PFC) controller that uses boost topology while operating in Continuous Conduction Mode (CCM). There is ...

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...

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 ...

Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...
