Design of a Hardware in the Loop scheme in DC-DC converters using LabVIEW FPGA

In this paper, the design and implementation of a Hardware in the Loop (HIL) scheme applied to DC-DC converters is presented. The HIL scheme is programmed in LabVIEW FPGA allowing to visualize and control the system parameters in real time. The case study is a Buck converter; a PWM generator and a digital PI controller are used to achieve the HIL. The validation of the HIL scheme is performed using a real Buck converter, considering variations and disturbances in the system to evaluate its performance.
