Abstract :
A digital control technique for voltage regulation module (VRM) is investigated, which is based on a predictive current regulator. Due to the adaptive-voltage-positioning (AVP) of the VRM, the controlled variable includes a combination of output voltage and inductor current. Besides the predictive regulator, a disturbance observer is used for compensation of input voltage variations and any other source of errors, such as dead-times, parameter and model mismatches. Even if aimed to an integrated digital controller, experimental investigation has been performed using discrete components, implementing the digital control in a field programmable gate array (FPGA). Experimental results on a synchronous buck DC-DC converter confirm the properties of the predictive control
