Abstract: Nine switch converters (NSCs) are power electronic devices that utilize nine power switches to convert electrical energy from one form to another. These converters are commonly used in various applications within the power industry. In fact, this type of converter is a multi-port power electronic device that consists of two three-phase terminals and a DC link, similar to the twelve-switch back-to-back (BTB) converter. However, it distinguishes itself by reducing the number of active switches by 25%. Nine switch converters offer several advantages over traditional converters. They can provide improved efficiency, reduced harmonic distortion and enhanced control capabilities. Additionally, they can handle higher power levels and operate at higher frequencies, making them suitable for a wide range of power industry applications. Furthermore, they are cost-effective, compact, and adaptable to higher power levels. By distributing voltage and current across fewer switches, the overall stress on individual components is reduced, which can enhance the lifespan and reliability of the converter. This paper summarizes the various utilizations of NSCs in modern power systems and briefly reviews the related challenges and future prospects.
