Title: Innovations by Reza Kheirollahi
Introduction
Reza Kheirollahi is an accomplished inventor based in Philadelphia, PA. He has made significant contributions to the field of electrical engineering, particularly in the development of solid-state circuit breakers. With a total of 4 patents, his work focuses on enhancing the efficiency and reliability of electrical systems.
Latest Patents
Kheirollahi's latest patents include innovative designs for active snubbers in solid-state circuit breakers. One patent describes two active snubbers for direct current (DC) solid-state circuit breakers (SSCBs): a metal-oxide-varistor with resistor-capacitor-switch (MOV-RCS) and an active-MOV with resistor-capacitor-diode (AMOV-RCD). These improved snubbers offer several advantages, 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, improving efficiency and reducing design costs. Experiments conducted on five prototypes demonstrate the effectiveness of these designs.
Another notable patent involves a solid-state DC breaker for medium voltage DC (MVDC) systems. This invention addresses the growing need for reliable DC electrical systems, especially with the rise of renewable energy resources. The proposed structure includes a main conduction branch with stacked MV Silicon-Carbide (SiC) devices to enhance efficiency and response time. Furthermore, it features a breaker branch with wireless capacitive coupling to avoid metal-to-metal contact, thereby increasing overall reliability.
