Resumen:

This work presents the design and implementation of a low-cost current source based on power electronics to test a power current relay. The topology of the system considers a three-phase, two-level inverter that works as three individual half-bridge single-phase converters. Additionally, a passive filter based on the LCL topology mitigates the high-frequency components of current signals. The inverter uses GaN wide bandgap transistors (Gallium Nitrite) type, which allows high efficiency and switching frequencies to achieve low-value passive components. The validation of the proposal considers experimental testing, taking quality measurements of current signals, and testing the power relay SEL-451 by setting the protections 50 and 51. © 2023 IEEE.
