Our Connecticut, USA business is celebrating the issue of SIX independently developed state of the art power electronics patents in close succession. We are excited to present an elegant new bidirectional resonant power architecture (US 11824459 B2) which forms the foundation for our collection of single stage power converter technologies (US 11722066 B2, US 11855544 B2, US 11811302 B1, US 11799385 B1, US 11855545 B2). Together, the technologies enable isolated bidirectional multi-port AC and DC power transmission (b) and energy storage with opportunities for improved efficiency and reduced material cost relative to prior art (a).
Comparison of novel single stage architecture to prior art multi-stage power architectures
Our foundational resonant power converter technology utilizes a novel synchronous phase control architecture which gracefully integrates the physics and tolerances of real-world power electronic components to result in linearized bidirectional power transfer with attenuated reactive current. The technology allows for the simultaneous control of line and transformer paths using an elegant synchronous modulation method implemented with a small parts count. The strikingly simple architecture is documented by the patent collection in electrical schematic form along with the fully descriptive advanced mathematics used in the invention, and simplified linear engineering relationships which enable power design.
Our technology is available for licensing and sale and includes published documentation. The collection of patents illustrates a number of embodiments of the presently invented technology including: isolated bidirectional DC/DC power conversion, power factor corrected AC/DC power converters, grid forming DC/AC power converters, solid state AC/AC power transformers with multi-port isolated DC busses, and fully generalized (AC & DC)/(DC & AC) regulators. Methods are also illustrated for current limiting, synchronization and power sharing between one or more power converters. Our novel architecture creates opportunities for cost savings and reliability due to low power and control part count, efficiency due a reduction in stages, and robustness due to isolated bidirectional local energy storage. We are excited to continue on our path to make advanced power technology accessible and welcome inquiries from interested partners.
