Predictive Control of an Indirect Matrix Converter

IEEE Transactions on Industrial Electronics, 2009
This paper presents the implementation of a predictive control scheme for an indirect matrix converter. The control scheme selects the switching state that minimizes the reactive power and the error in the output currents according to their reference values.

Comparison of Two Overmodulation Strategies in an Indirect Matrix Converter

IEEE Transactions on Industrial Electronics, 2013
This paper discusses two overmodulation controls, namely, square wave and trapezoidal, in the indirect matrix converter (IMC) for motor drive application. The differences between these two modulations are analyzed based on the output-input voltage transfer ratio (VTR), the efficiency, and the current total harmonic distortions under two load conditions.

Current Control for an Indirect Matrix Converter With Filter Resonance Mitigation

IEEE Transactions on Industrial Electronics, 2012
A predictive control scheme for the indirect matrix converter including a method to mitigate the resonance effect of the input filter is presented. A discrete-time model of the converter, the input filter, and the load is used to predict the behavior of the instantaneous input reactive power and the output currents for each valid switching state.

Indirect Matrix Converters' Enhanced Commutation Method

IEEE Transactions on Industrial Electronics, 2015
This paper introduces an enhanced commutation method applied to the indirect matrix converter topology. It is based on the detection of the load current polarity so as to cancel the turn-on delay times of the load-side converter's switches. The proposed method allows the grid-side converter devices to commutate at zero current with larger time interval

High efficiency Indirect Matrix Converter topologies

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
This paper discusses new three-phase ac-ac Indirect Matrix Converter (IMC) topologies featuring higher power efficiency than conventional IMCs. Initially, a new Inverting-link Matrix Converter (ILMC) with lower conduction power losses than a standard ILMC for voltage step-down operation is proposed.
