Imposed Sinusoidal Source and Load Currents for an Indirect Matrix Converter

IEEE Transactions on Industrial Electronics, 2012
A new strategy for indirect matrix converters which allows an optimal control of source and load currents is presented in this paper. This method uses the commutation state of the converter in the subsequent sampling time according to an optimization algorithm given by a simple cost functional and the discrete system model.
