People usually research modulation mode 3 of SVM for matrix converter discussed in this paper. Actually, other different modulation modes of SVM for matrix converter are worth studying. Two novel modulation modes are put forward for matrix converter for the first time in this paper, expanding its modulation modes of SVM. First, SVM for matrix converter is described. Then the 3 modulation modes ...

The matrix converter system is competitive solution to replace the conventional two stage ac to ac converter. In this paper, a matrix converter driving a speed-controlled induction machine is examined under open-switch fault. First, a-predictive direct torque method is proposed using only the motor torque and current. Second, a motor speed control is presented. The proposed techniques do not re...

A simplified 5-RC transmission line equivalent circuit was introduced. Manganese dioxide cathodes from three commercial primary alkaline cells were investigated by means of ac impedance technique. Cathode Ohmic resistance, Faraday resistance for the reduction of MnO2, proton diffusion rate inside the lattice of EMD and electrochemical accessible surface area were obtained by numerical fitting o...
