Single-phase to Three-phase Multilevel Matrix Converter ($1\times 3 \ \mathrm{M}^{2}\mathrm{C}$) for Induction Motor Drive

Abstract

Single-phase to Three-phase Multilevel Matrix Converter ($1\times 3 \ \mathrm{M}^{2}\mathrm{C}$) is presented in this paper. This converter connects a single-phase supply to a three-phase load directly with absence of any energy storage device (battery) or any heavy dc-link capacitor. The whole system promises the characteristics of the conventional matrix converter like balance operation and unity power factor (UPF). For analysis purpose a three-phase induction motor is modeled in simulation environment supplied by $1\times 3 \ \mathrm{M}^{2}\mathrm{C}$>. The $1\times 3 \ \mathrm{M}^{2}\mathrm{C}$> consists of source side current source rectifier (CSR), and load side three-phase three-level diode clamped inverter (3L-DCI). Complete modulation scheme to control the CSR and multilevel 3L-DCI in decoupled manner in order to simplify complexities of modulation of the $1\times 3 \ \mathrm{M}^{2}\mathrm{C}$> is presented in this paper. The performance of $1\times 3 \ \mathrm{M}^{2}\mathrm{C}$> driven three-phase induction motor is analyzed in MATLAB/Simulink environment and compared it with two level matrix converter with valid results are also given in the paper.
