Název v původním jazyce

A time-domain analytical analysis of three-phase voltage source inverter with space-vector PWM

Popis výsledku v původním jazyce

A new mathematical method for time-domain analysis of power converters with periodic pulse width modulation (PWM) is proposed. The method is based on mixed p-z description of linear periodically time-varying system. The model was used for the analysis ofthree-phase voltage source inverters with Space Vector PWM feeding a three-phase static load, but it is applicable for all types of converters with an explicitly determined output voltage (converters with forced commutation) and periodical modulation. The mathematical model uses the Laplace and modified Z transform. The solution is not dependent on the number of the pulses of the PWM pattern. Instead of solution of algebraic equations for the initial current conditions the change of switching instantsis reflected in the solution only by a change in two values mk and nk. 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.
