Architecture reduces component count in 500W to 10kW conversion applications
AC/DC converter technology introduced by Eggtronic at CES 2023 in Las Vegas is claimed to reduce component count and improve EMI performance in high power applications requiring power factor correction (PFC).
The ClassEgg technology is a patented, zero voltage switching (ZVS) converter implementation derived from the traditional boost PFC + LLC resonant power converter. It improves the conventional boost PFC by taking advantage of a proprietary magnetic component to ensure ZVS, lower EMI and reduced component count, to drives down losses while offering performance higher than interleaved solutions, said Eggtronic. The cost is the same as a standard boost PFC, said the company.
It is also reported to offer better performance and lower component count than standard LLC resonant converters, via a patented rectifier and control algorithm that ensures multiple regulated outputs and high efficiency simultaneously.
The combination boost PFC + LLC controller can be used across a variety of input and output voltages and between 10 per cent and full load, making it suitable for use in power supplies for TV panels, PCs, servers and large home appliances as well as power conversion in electric and hybrid vehicles and solar panel inverters.
“ClassEgg represents a step forward in combo boost PFC + LLC power design for higher power applications,” said Igor Spinella, Eggtronic’s founder and CEO. “Using ZVS to ensure maximum efficiency across the broadest possible load range, ClassEgg allows developers of next-generation, high-power applications to minimise energy use for sustainable operation while delivering high performance, optimised power densities and simplified EMC design”.
Eggtronic was founded in 2012 and is based in San Francisco, Modena, Italy, Taipei and Guangzhou. It develops cutting-edge, environmentally friendly and energy-efficient technologies, with more than 300 international patents granted worldwide. In 2020 it introduced its ICs division.
The company serves customers in the consumer, automotive, or industrial market sectors.
