Hardware-In-the-Loop Simulation of a Step-Up Converter Using the GDS Oversampling Technique in a Microcontroller

The objective of this work is the implementation and experimental validation of a high frequency sampling technique for switch gate drive signals, known as Gate Drive Signal Over-sampling (GDS Oversampling). This technique allows a static power converter to be simulated in real time with an integration step of the same order of magnitude as the switching period. The implementation is carried out in a Texas Instruments F28379D microcontroller, and for validation purposes a Hardware-In-the-Loop (HIL) simulation of a Step-Up converter is performed. In this HIL configuration, one core of the microcontroller is responsible for simulating the converter, using an average model, while the other core is responsible for controlling the converter. Finally, the obtained results are compared with an offline simulation carried out entirely in PSIM.
