Title: Innovations of Zheng John Shen

Introduction

Zheng John Shen is a notable inventor based in Oviedo, Florida, with a remarkable portfolio of 11 patents. His work primarily focuses on advancements in electrical engineering, particularly in circuit breaker technology and smart devices.

Latest Patents

One of his latest patents is the "Hybrid circuit breaker using a transient commutation current injector circuit." This innovative circuit breaker features a first current path that includes a mechanical switch, such as an ultrafast mechanical switch, and a second current path that is connected in parallel. The second path incorporates a current injector, which is a transient commutation current injection circuit, in series with a bidirectional power electronic switch. This design allows for the communication of short circuit fault current from the mechanical switch path to the electronic path via current injection, followed by the interruption of the fault current. The system generates a pulse current to the electronic switch in the second current path, ensuring that the mechanical switch opens during the pulse current. This method effectively reduces or eliminates arcing when the mechanical switch is opened.

Another significant patent is the "Solid state protective smart plug device." This wireless-controlled smart plug device utilizes a solid state switch to deliver electrical power from an outlet to a load while providing protection against overload, short circuit, ground, arc, or voltage surge faults. The switch consists of a bidirectional semiconductor switch with two back-to-back connected transistors, such as silicon power MOSFETs, silicon insulated-gate bipolar transistors (IGBTs), silicon carbide (SiC) transistors, or gallium nitride (GaN) transistors. Each transistor is configured to control the current flow from the electrical receptacle to the external electrical load.
