Introduction

Juncheng Lu is a prominent inventor based in Flint, MI (US), known for his contributions to electric power conversion technologies. With a total of 7 patents to his name, Lu has made significant advancements in the field, particularly in the development of apparatuses that enhance the efficiency and functionality of power conversion systems.

Latest Patents

One of Lu's latest patents is an "Electric power conversion apparatus having single-phase and multi-phase operation modes." This innovative AC/DC conversion apparatus features first, second, and third AC/DC conversion modules that are operated by a controller in two distinct modes. In the first mode, the input AC signal is 3-phase, allowing each of the three modules to handle a respective input phase. In the second mode, the input AC signal is single-phase, enabling the first and second modules to deliver output power based on the single-phase AC input. The controller actuates H-bridge switches in the third module, which is connected to active filter circuitry designed to reduce the AC component in the output signal. This active filter circuitry can be selectively connected to the H-bridge switches when single-phase operation is desired.

Another notable patent is the "Hybrid switch including GaN HEMT and MOSFET." This hybrid switch apparatus comprises a gate drive circuit that produces a gate drive signal. It features a GaN high electron mobility transistor (HEMT) and a silicon (Si) MOSFET connected in a parallel arrangement. The design allows for efficient operation by ensuring that the first drain and second drain are electrically connected, as well as the first source and second source. The second gate is connected to the gate drive circuit output to receive the gate drive signal, while a delay block produces a delayed gate drive signal for driving the GaN HEMT.
