Description
Summary:This paper describes a complete digital controlled dc-dc buck converter performed by FPGA circuitry. All tasks as are analog to digital conversion, control algorithm and pulse width modulation were implemented in the FPGA. This approach enables high-speed dynamic response and programmability of the controller without external passive components and more the controller structure could be changed from linear to non-linear easily also without external components. The applied algorithm enables the switching frequency of 100 kHz.
