Introduction

Xianshi Wen is an inventor based in Foshan, China. His work includes power-conversion control methods designed to manage electrical faults and regulate voltage. He is associated with 3 patents.

Latest Patents

Wen’s listed recent patents address control and voltage regulation in power systems.

“Control method, device, system and storage medium” describes a method for responding to a target-type fault in a three-phase, three-level power supply circuit. A first control device determines a signal instructing a first load to stop operating when the fault is associated with a second load connected across two circuit buses. The signal is sent to a second control device, which controls the first load.

“Voltage control method and apparatus, household device, computer storage medium, and computer program” concerns voltage regulation in a three-level converter. The method obtains the two half-bus voltages, their overvoltage protection limits, and the voltage required by a load. It selects a control strategy that adjusts a switch’s output duty ratio, helping ensure that the voltage supplying the load meets its requirement while both half-bus voltages remain within their protection limits.
