Latest Patents

One of Song Chi's latest patents is titled "System and method for hybrid energy conversion." This invention discloses a system and method for conditioning DC power received from hybrid DC power sources. The power conversion circuit is designed to selectively condition the output power generated by the DC power sources to a DC bus voltage. It includes a switch arrangement and capacitors that provide charge balancing within the circuit. A controller, in operable communication with the switch arrangement, receives inputs on the DC bus voltage and parameters related to the operation of the DC power source. Based on these inputs, the controller determines an adjustable voltage to be output from the conversion circuit to the DC bus and selectively controls the operation of the switch arrangement to generate the determined voltage.

Another notable patent is the "Switching amplifier and method for operating same." This method is utilized for operating a switching amplifier that consists of a plurality of cascade elements. The method involves coupling the cascade elements in series between two terminals of a load and providing two leg circuits comprised of switches in each of the cascade elements. All switches in the switching amplifier are controlled using space vector modulation (SVM), ensuring that the change of a common mode (CM) voltage generated by the amplifier remains within a predetermined range.
