Brief description of the technology solution and the added value it provides <\/strong><\/h4>\n

Power converters with the same nominal power may process very different “internal” or “indirect” power, which is the metric that determines their volume, weight and losses. The fundamental lower limit of this “indirect power” may be calculated, and defined as “Differential Power”.<\/p>\n

“3-port Power converters” required in energy buffered architectures for PV panels, batteries and renewable energy can be designed with a 2x reduction in losses, weight and volume.<\/p>\n

Description of the technological base<\/strong><\/h4>\n

A single-stage power converter replaces the typical 2 stage architectures, either cascaded of with Parallel Active Filter.<\/p>\n

The power converter is synthesized besed on the Fundamental Limit of indirect power. The proposed topology is a 3-level inverter,  but the flying capacitor is used also as line frequency storage capacitor.  This is the key innovation.<\/p>\n

The “indirect” power processed by the power components is half of the power processed by state of the art architectures, which yields a 2x factor reduction in losses, weight and volumen.<\/p>\n
