Title: Kun Dou: Innovator in Power Conversion Technology
Introduction
Kun Dou is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of power conversion technology, holding a total of 2 patents. His work focuses on improving the efficiency and control of converters, which are essential components in various electrical systems.
Latest Patents
One of Kun Dou's latest patents is titled "Carrier phase control for polyphase rectifier or inverter." This invention provides a method for controlling a converter and a converter system. The method involves obtaining voltage signals that indicate phase voltages of three phases at the AC side of a converter. It determines carrier signals for the three-phase switching branches of the converter, ensuring that two of the three phases have the same phase while differing from the third phase. The magnitude of the phase voltage of the third phase is positioned between the phase voltages of the other two phases. This innovation generates control signals for the three-phase switching branch based on the determined carrier signals and modulation wave signals.
Another notable patent is the "Driving circuit device and driving method of totem-pole power factor correction converter." This invention includes a driving circuit device for a totem pole power factor correction converter (PFC). It features a controller that manages the initial drive level of a switching tube, a current judgment circuit that assesses whether the inductive current crosses zero, and a selector that compares the power supply voltage with zero. The device generates a target drive level for driving the switching tube through logical operations on the intermediate control level and the initial drive level.
