SANABRIA-ROJAS, Jeimy C.; BARRERA-LEGUIZAMON, Daniel M.  and  BAUTISTA-LOPEZ, Diego A.. Design and implementation of a CSI inverter with unipolar SPWM modulation and PR controller for lineal loads. Dyna rev.fac.nac.minas [online]. 2021, vol.88, n.219, pp.85-93.  Epub Mar 14, 2022. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v88n219.93100.

This paper presents a detailed implementation of a current source inverter using unipolar sinusoidal pulse width modulation. This method is uncommon in these types of inverters and the semiconductor devices, integrated circuits, sensors, and filters used in conjunction with the TMS320F28379D microcontroller will be discussed. The inverter was tested in both an open and closed loop with a proportional resonant controller. Satisfactory results in terms of the harmonic distortion factor at the voltage output and the regulation indices for lineal loads were obtained. The response circuit demonstrated its viability for the subsequent connection to an electrical distribution network.

Keywords : CSI; implementation; inverter; proportional-resonant controller; unipolar; SPWM modulation.
