| Abstract: | Conventional matrix converter has the advantages of no DC capacity,bidirectional power flowing,adjustable input power factor and pure sine waveforms at line and load sides.However,commutation problem is complicated.A new direct torque control(DTC) for electrically excited synchronous motor(ESM) supplied by indirect matrix converter(IMC) was investigated,where,the rectify stage controls the input power factor,the inversion stage controls torque and stator flux linkage,and all bidirectional switches at line side turn on and turn off at zero current by inserting zero voltage vector at the inverter side.The experimental results are provided to verify its feasibility. |
