A simple CB-PWM technique for five-phase matrix converters including over-modulation mode

摘要

This paper presents a simple carrier-based PWM (CBPWM) technique to control a three-phase to five-phase matrix converter (3×5 MC). The proposed technique is based on the indirect configuration of the matrix converter in which the three to five-phase matrix converter is modeled as three-phase rectifier followed by a five-phase inverter. With this representation, CBPWM technique is suggested to control both stages in both linear and over-modulation modes. Using the proposed modulation technique, the maximum possible voltage transfer ratio (VTR) of the converter in the linear and over-modulation modes is achieved. The proposed modulation technique is modeled using Matlab/Simulink software and the overall system algorithms are compiled to a real time system based on DS1104 controller. A sample of the obtained experimental results is presented to support the viability of implemented three to five-phase matrix converter with the proposed modulation technique.
