MODENA, Italy, Dec. 6, 2021 /PRNewswire-PRWeb/ -- Eggtronic has announced QuarEgg+™, an innovative, proprietary power architecture that significantly improves the efficiency and reduces the size of AC/DC converters that would traditionally have used active clamp flyback (ACF) and quasi-resonant (QR) topologies. The new architecture will maximize the performance, minimize the form factor and improve the reliability of AC/DC power schemes in applications ranging from fast chargers and adapters for mobile devices and laptops to power supplies for loudspeakers and smart home assistants.

QuarEgg+ is the first in a series of power conversion architectures that make up the Eggtronic EcoVoltas® family. Specifically developed to deliver smaller, higher efficiency power conversion, this family of proprietary, patented technologies will help engineers to meet performance, cost, size, weight and sustainability goals. EcoVoltas solutions boost the performance of FET switching devices, whether they are based on legacy silicon or wide bandgap (WBG) materials such as gallium nitride (GaN) and silicon carbide (SiC). They also drive down no-load 'vampire' power and reduce the overall Bill of Materials (BoM).

Thanks to EcoVoltas QuarEgg+ technology, designers of low-power AC/DC power conversion applications can now address the most stringent performance, size and cost criteria while contributing to sustainability goals by driving down power use and associated emissions.

Because QuarEgg+ offers superior performance to conventional ACF and QR conversion topologies, it enables power converters that are up to seven times more efficient and three times smaller than traditional silicon converters and up to three times more efficient and twice as small as previous GaN converters.

QuarEgg+ operates with Zero Voltage Switching (ZVS) under all load conditions to give very flat light-load-to-full-load efficiency curves. Efficiencies are up to 95% at full load and up to 92% at light load. Power consumption is further reduced thanks to the ultra-low standby power of less than 18 mW. Elimination of a high-voltage, high-side clamping MOSFET minimizes component count and improves reliability, while smooth transient response reduces EMI to simplify filtering requirements.

To help speed the development of AC/DC applications built on QuarEgg+ technology, Eggtronic will be offering both GaN-based and silicon-based QuarEgg+ products with power outputs of 35 W, 45 W and 60 W. Output options include USB PD, fixed voltage and CC CV. Development boards, integrated power controllers, a range of proprietary magnetic components and comprehensive technical support will also be available.

Discussing the new architecture, Igor Spinella, Eggtronic's CEO and founder comments: "Thanks to EcoVoltas QuarEgg+ technology, designers of low-power AC/DC power conversion applications can now address the most stringent performance, size and cost criteria while contributing to sustainability goals by driving down power use and associated emissions."
