RT info:eu-repo/semantics/article T1 A SiC-MOSFET bidirectional switch solution for direct matrix converter topologies A1 Lezcano Delvalle, Hugo Hernán A1 Romero Vega, Rodrigo Nicolás A1 Núñez Aquino, Sergio Eduardo A1 Sanabria Morel, Bruno Roberto A1 Palacios Pereira, Fabian A1 Maqueda Acuña, Edgar Marcial A1 Toledo Gallardo, Sergio Ramón A1 Pacher Vega, Julio César A1 Caballero Morilla, David Domingo A1 Gregor Recalde, Raúl Igmar A1 Rivera Abarca, Marco Esteban AB Bidirectional switches are highly required power electronics units for the design of power converters, especially for direct matrix converters. This article presents the design and implementation of a compact bidirectional switch based on SiC-MOSFET technology, aimed at high-efficiency, high-density power electronics applications. The proposed architecture employs surface-mount components, optimizing both the occupied area and electrical performance. The selected switching device is the IMBG120R053M2H from Infineon, a SiC-MOSFET known for its low on-resistance, high reverse-voltage blocking capability, and excellent switching speed. To drive the power devices, the UCC21521 gate driver integrates two independent isolated outputs in a single package, enabling precise control and reduced electromagnetic interference (EMI). The developed design supports bidirectional current conduction and voltage blocking, offering a robust and scalable solution for next-generation power converters. Design criteria, simulation results, and experimental validations are discussed.
