Title: Cheng Luo: Innovator in Power Conversion Technologies
Introduction
Cheng Luo is a prominent inventor based in Pittsburgh, PA (US), known for his contributions to power conversion technologies. With a total of 2 patents, he has made significant advancements in the field of electrical engineering.
Latest Patents
One of Cheng Luo's latest patents is focused on pulse width modulation (PWM) for multi-level power inverters. This invention provides a method for controlling the operation of semiconductor gates in a power conversion system that includes one or more multilevel inverters. The method involves generating a control signal responsive to the output current power factor associated with the inverters. It produces a discontinuous pulse width modulation reference signal based on the control signal and a target output power. This reference signal indicates a shift in the phase angle between current and voltage, allowing for the generation of a gating signal that adjusts the phase angle to prevent switching of the semiconductor gates.
Another notable patent is for load commutated inverter drive systems designed for high power drive applications. This system includes a first supply bridge and a second supply bridge, each comprising an AC-to-DC source side converter, a DC link circuit, and a DC-to-AC load side inverter. The system features a controller that selectively controls the supply bridges through the firing of silicon controlled rectifiers (SCRs). The electrical power output from both supply bridges is combined and supplied to a synchronous electrical machine, enhancing the efficiency of power delivery.
