Digital Voltage Control of DC-DC Boost Converter

The need for digital control for faster communication between power stage module & system controllers is\ud increased with requirement of load complexity. The requirements also include stability of power module with the\ud parametric variation. This paper presents a digital control of a dc-dc boost converter under nominal parameter\ud conditions. The system controller has been verified in both frequency response as well as MATLAB-Simulink\ud under nominal & parametric varying condition. The modeling of converter has been illustrated using state-space\ud averaging technique. Direct digital design method is equipped to design the controller in frequency response to\ud yield constant load voltage. The characteristic of load voltage before & after parametric variation is shown
