What changed

This document is a publication of a patent application filed by Wi-Charge Ltd. for an "EFFICIENT WIRELESS POWER RECEIVER." The application describes a two-mode DC/DC converter system that allows conventional logic circuits to efficiently drive DC/DC converter circuits even when powered by low voltages (below 1V) from sources such as photovoltaic cells. It details how a simple control module can operate at low voltages, and once a sufficient output voltage (above 1.5V) is achieved, a more complex controller takes over for increased efficiency and adaptability.

As this is a patent application publication, there are no immediate compliance obligations or deadlines for regulated entities. However, companies involved in wireless power transmission, photovoltaic systems, or power management technologies may wish to review the application for potential intellectual property insights or competitive intelligence. The filing date was September 12, 2023.

Abstract

A two-mode DC/DC converter systems, for use in wireless power transmission receivers, and which allow the use of conventional logic circuits, operating at voltages well over IV, to efficiently drive DC/DC converter circuits even while being powered from the low voltage, even below IV, of a photovoltaic cell output. Two separate control modules may control the DC/DC converter, a first using a simple control for switching the converter, capable of being powered by the low voltages generated by the PV. Once a voltage above about 1.5V is generated at the output of the DC/DC converter, a second, more complex controller can become powered up, and takes control of the voltage conversion process, driving the converter more efficiently, and able to adapt its control function according to logical input instructions and sensor outputs received. The complex controller can operate independently, or in conjunction with the simple controller, to increase efficiency further.
