Model Predictive Control of a Z-Source Power Converter for Wireless Power Transfer Applications
This paper presents a Model Predictive Control (MPC) algorithm applied to a Z-Source Inverter (ZSI), used in Wireless Power Transfer Systems (WPTs). The suggested control scheme is based on measurements of the ZSI capacitor voltage and the current load, to predict and tracking them in order to maintain the output voltage at the desired value. The modeling of the converter, along with the compensation circuit, the control scheme, and the PWM, are presented. Time-domain simulations are carried-out to validate the MPC-based scheme, which is compared with a Linear Quadratic Regulator (LQR).
