A General Mathematical Model Based on Laplace and Modified Z-Transform for Time and Frequency Domain Investigation of Three-Phase Switched Circuits
Original language description
A general mathematical method for both the time-domain and frequency domain analysis of power converters with periodic switching cuircuits is proposed .The method is based on mixed using of the Laúlace and modified Z-Transform in linear periodically time-varying system. The model was used for the analysis of three-phase voltage source inverters with Space Vector PWM feeding a three-phase static load, or an induction motor drive but it is applicable for all types of converters with an explicitly determined output voltage (converters with forced commutation) and periodical modulation..From the modulated waveforms we can easily obtained equations for the six step waveforms.The derived equations are validated using a 3 kW three-phase inverter.
