Abstract
- Highlights • A full-order switched model is developed for a HF-Link Grid-Connected Inverter. • A full-order Generalized Average Model (GAM) is derived for the Converter. • The developed GAM in the Complex Fourier domain reproduces the mos relevant system dynamics. • The switched and Averaged models are validated with experimental results. Abstract Full-order switched and time-continuous models for a High-Frequency Link Grid-Connected DC/AC converter are presented in this paper. The configuration is DAB-based, therefore its transformer leakage inductor current is purely AC as well as the remaining grid-side voltages and current; representing a challenge to obtain an average or time-continuos model, simpler for simulation tasks as well as for controller analysis. The presented average model is based on the DC and first harmonic terms of the complex Fourier representation of the derived full-order switched model. Simulation results are corroborated through experimental results, showing the validity of the presented full-order time-continuous model. [ABSTRACT FROM AUTHOR]
