Abstract
DC-DC converters find variety of applications in modern gadgets like cell phones, laptops, converter chargers, etc. Digital controllers have an advantage over analog controllers in terms of better accuracy, less power consumption, less noise, high speed, better reliability, and feasibility of real-time applications. This paper presents a digital PI controller for a DC-DC buck converter. The controller is designed on a VLSI-based field programmable gate array (FPGA) platform. A VHDL code is written for the hardware of the control loop consisting of a comparator, PI controller, and a PWM generator. The ADC is interfaced through the FPGA. The hardware is tested using a Spartan-3 XC3S5000-FG900 Development Board.
