HVICs Enable 98% Efficient PFC Designs Up to 550W

APEC 2017

March 28, 2017

Power Integrations today announced its HiperPFSTM-4 family of power factor correction (PFC) high-voltage ICs. The new device family serves applications targeting excellent efficiency and power factor performance at both full load and light load conditions. HiperPFS-4 devices incorporate a 600V MOSFET suitable for 305Vac input and a high efficiency, variable frequency, CCM PFC controller in a single, compact, electrically isolated, heatsinkable package. The IC family delivers high power factor, low THD and uniformly high efficiency across a wide output load range, allowing OEMs to meet the demanding 80 PLUS® Platinum and Titanium power supply standards.

The Future of Electricity

Richard Zhang
Technology Executive, GE Power Conversion

We are living in a dynamic global power environment. We all need the same thing—affordable, sustainable, reliable power, and the demand is growing. While the power sector is leading the way towards a decarbonized energy system, electricity gains ground in many sectors and will make up about 25 percent of final energy consumption by 2040, as estimated by IEA.

GaN enables Wide-Input and Compact 12W DC-DCs

In the last couple of years, a team of researchers at DTU Electrical Engineering have worked to develop the world's smallest power supply unit called TinyPower together with a number of companies. The initial purpose was to produce a power supply unit which could be used in LED light bulbs or light sensors. The development of the TinyPower power supply unit will mean an expected improvement in service life, cost, size, and weight. In future, wireless energy harvested from renewable energy sources is to run the world's smallest power supply unit, making it possible to use it for small new devices sewn into clothes and other wearable and IoT applications.
