Title: Junming Liang’s Inverter Power Module Patents.

Introduction

Junming Liang is an inventor based in Kokomo, Indiana, whose patent work concerns power module assemblies for electrical inverters. His inventions address ways to convert direct-current (DC) power into alternating-current (AC) power for motor applications. Liang is associated with BorgWarner US Technologies LLC and holds 2 patents.

Latest Patents

Both of Liang’s listed patents are titled “Systems for Power Module Assembly for Inverter.” They describe inverter architectures that supply AC power to motor windings from a DC voltage source.

One patent describes an inverter with a power module containing switches for two phases. Positive DC power tabs connect to a positive rail and supply the phase switches, while negative DC power tabs connect to a negative rail. Separate AC power tabs receive output from the switches for each phase. This arrangement provides a structured approach to connecting DC rails, switching components, and AC outputs within an inverter.

The other patent describes a system with two inverters connected to opposite ends of a motor winding. Each inverter is connected to the voltage source and supplies AC power to its respective end of the winding. The power module also includes a changeover switch that selectively connects or disconnects the winding’s second end from a neutral connection.

Career Highlights

Liang’s listed patent portfolio focuses on inverter power module design and motor-drive systems. The disclosed arrangements address electrical connections and switching configurations that support the delivery of AC power to motor windings.
