Variable-speed multiphase drive systems have become an increasingly important topics compared with conventional three-phase one due to their distinct advantages. This study presents a new pulse width modulation (PWM) technique for controlling the three-to-five phase matrix converter to reduce the commutation number of the power switches and the total harmonic distortion, simultaneously. The proposed...
Matrix electric power conversion topologies and their switch functions are flexible, as can be used to derive other electric power conversion topologies and switch functions for specific applications. This paper presents the Single Phase Matrix Converter (SPMC) topology that will operate as rectifier, inverter, buck converter, boost converter, chopper and cycloconverter. The circuit composed from...
This paper presents an implementation of controlled rectifier with power factor correction (PFC) using single-phase matrix converter (SPMC). A current control loop (CCL) using standard proportional integral control was used to implement PFC to correct the pulsating nature of the input current to almost unity power factor form with low total harmonic distortion (THD) level well below the acceptable...
The devices of power used in matrix converters (M.C.) need some operation sequences to commute the current in a safe way. These operation sequences are what we denominate strategies of current commutation, being these more complex than in other converters. In this article a comparative analysis of the different strategies of current commutation will be carried out by means of simulation and they will...
The proposed space-vector modulation scheme for dual-bridge matrix converters uses the principle of the indirect modulation strategy to calculate the duty cycles of the active vectors. On the other hand, zero-vectors duration and distribution within a switching cycle are elaborated such that the line side switches commutate at zero-current leading to safe commutation of the converter. The switching...
