Totem-pole power factor correction (PFC) is a simple and highly efficient topology. It is being widely used in high-density and high-efficiency power supply design. However, engineers still face many design challenges, including PFC current reversing prevention at input voltage drop, lightning surge protection, current harmonic reduction, and ac crossover current spike … [Read more...] about Totem-Pole PFC Reliability and Performance Improvement With Advanced Controls

Supercapacitor Assisted Surge Absorber Technique: high performance transient surge protectors for consumer electronics
Invention of the transistor in 1947 made a radical change to the path of the development of electronic products and systems. In the mid-1950s, integrated circuits (ICs) started evolving rapidly, creating miniaturized analog, digital and mixed signal circuits. By the 1960s to 1970s, microprocessors, memories and power semiconductors entered the electronic marketplace. During the … [Read more...] about Supercapacitor Assisted Surge Absorber Technique: high performance transient surge protectors for consumer electronics
