Modeling of Boost Converter-based Electronic Load with Energy Recycling Capability

Modeling and control of an active electronic load with energy recycling capability is presented in this paper. The system is composed of a boost DC-DC converter and a grid-connected signal phase inverter. The boost converter control system follows the input current reference set by the user, while the inverter control system maintains a constant DC-link voltage by controlling the current injected into the grid. The grid current harmonic content is filtered by an LCL filter. The model of the converters and the control system is implemented in MATLAB/Simulink. Simulation results demonstrate the proper operation of the conversion system.
