The paper deals with two phase systems with orthogonal output voltages and currents. The investigated systems are power electronic converters supplying alternating motors. Output voltages of them are strongly non-harmonic ones, so they must be pulse-modulated due to requested nearly sinusoidal currents with low total harmonic distortion. Simulation experiment results of halfbridge matrix converter for both steady- and transient states for SMPM and IM motors are given in the paper, also experimental verification under R-L load, so far. The results worked-out confirm a very good time-waveform of the phase current and the system seems to be suitable for low-cost application in automotive/aerospace industries and application with high frequency voltage sources. |
