This article presents the topology, large and small signal analysis of the mathematical model, sizing of passive components and design of a proportional resonant controller for a Current Source Inverter. The performance of the inverter controller was verified by simulation, obtaining satisfactory results in terms of the harmonic distortion factor in the voltage output and the regulation indices for the load with values close to the operating point. The response of the control system in static considerations and operation dynamic demonstrated its viability for electronic implementation in the future.
