Title: Fei Lu: Innovator in Solid-State Circuit Breaker Technology
Introduction
Fei Lu is a prominent inventor based in Wynnewood, PA (US), known for his contributions to the field of solid-state circuit breakers. With a total of 5 patents, he has made significant advancements in improving the efficiency and reliability of electrical systems.
Latest Patents
One of his latest patents focuses on active snubbers for solid-state circuit breakers to enhance switch voltage utilization rates. This innovation includes two types of active snubbers for direct current (DC) solid-state circuit breakers (SSCBs): the metal-oxide-varistor with resistor-capacitor-switch (MOV-RCS) and the active-MOV with resistor-capacitor-diode (AMOV-RCD). The design allows for either half- or full-controlled switches, resulting in four different topologies. The improved snubbers provide several benefits, such as disconnecting the MOV from the power line during the SSCB OFF-state, which enhances reliability. Additionally, the voltage utilization rate of the main switch is significantly increased, leading to improved efficiency and reduced design costs. Experiments conducted on five prototypes, including four proposed snubbers and a comparison with the conventional MOV-RCD snubber, demonstrate these advancements.
Another notable patent by Fei Lu is a solid-state circuit breaker based on wireless coupling and resonant circuits for medium voltage DC (MVDC) systems. As renewable energy resources and DC supplied loads grow rapidly, DC electrical systems have gained global attention. The proposed solid-state DC breaker addresses the challenges of reliability and efficiency in medium voltage DC systems. The design features a main conduction branch with stacked MV Silicon-Carbide (SiC) devices for improved efficiency and fast response times. Additionally, a breaker branch utilizes wireless capacitive coupling to avoid metal-to-metal contact, enhancing overall reliability.
