Finite states-modulated model predictive control of a Quasi-z-Source Inverter with LCL filter

This paper presents a new Modulated Model Predictive Control (M
²
PC) scheme for a three phase Quasi-Impedance Source Inverter (QZSI). This scheme is the result of a delay error compensation implementation in an M
²
PC algorithm for a QZSI, and a technique to achieve fixed switching frequency for the ease of a passive LCL filter design. The transient and steady state response of the proposed algorithm is validated through simulation. The introduced control technique for a QZSI can be considered for further development of a reliable and efficient power converter suitable for renewable energy systems.
