RESUMO

This work investigates the utilization of a predictive digital current-mode controller for a bidirectional DC-DC converter connected to a photovoltaic electric generation system. The DC-DC converter, with the digital current control, operates as a high performance battery charger system, enabling long battery life by providing precision charging control, constant monitoring and fast protection. Digital modeling of the converter and the controller are presented and discussed. Simulation results are used to validate the design controller procedures. The digital currentmode control was implemented in the TMS320F2812 DSP of Texas Instruments
