Title: Hong Liu: Innovator in Resonant Converter Technology
Introduction
Hong Liu is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of electrical engineering, particularly in the development of resonant converters. With a total of 3 patents, Liu's work showcases his expertise and innovative spirit.
Latest Patents
Liu's latest patents include a resonant converter and a method for controlling the resonant converter. This application discloses a resonant converter that consists of a resonant tank, a first circuit connected to one end of the tank, and a second circuit connected to the other end. The first circuit includes at least one primary switch, while the second circuit features at least one controllable switch. The method involves controlling the controllable switch based on a secondary initial switching frequency, allowing the second circuit to output power effectively.
Another notable patent is the non-communication distributed control method and device for a cascade system. This method regulates an AC current of the power module by taking the output of a closed-loop control as a reference value for the bridge arm voltage. The amplitude of the bridge arm voltage is used as a feedback signal, which is adjusted in conjunction with the AC current of the power module. This innovative approach ensures that the parameters reflecting active current maintain a monotonic relationship with the amplitude of the bridge arm voltage.
