El inversor dual buck de inductor simple: control de voltaje y procedimiento para obtener su modelo matemático.

In this article, the procedure to obtain the mathematical model for a 2 KW DBI (Dual Buck Inverter) converter, which can be used in renewable energy applications, is described. In the same way, the operation modes of this inverter are described with the respective equations that model its behavior for each one of them and, with the activation signals of the MOSFETs present in the inverter, the switched model is created. The linearization procedure of the model at one operating point is shown, simulation results are recorded in Matlab®/Simulink™ using PID controller, making changes in both load and input DC voltage levels for the proposed model and for the inverter circuit, thus making use of discrete elements. The total harmonic distortion in the output voltage signal is less than 0.73%, complying with the IEEE 519 standard.} [ABSTRACT FROM AUTHOR]
