| Notes | Power predictive control（ PPC） was applied to single-phase voltage source converters,with the actual single-phase input current and voltage,and a virtual quartered current and voltage were constructed using second-order generalized integrator（ SOGI）. Based on these electric parameters,a αβ coordinate system was formed. The mathematical model of the two phase stationary and two phase rotating coordinate frame were established respectively for single-phase voltage source converters. The instantaneous power model of rotating coordinate frame was deduced and analyzed. The instantaneous power model was used to predict the controlling voltage of the converters,and a trigger pulse was generated to control the converters. The control strategy has some characteristics,such as easy designing,fixed switching frequency,no need to adjust parameters of controller,with fast step response of the power,and realizing decoupled power control. The feasibility and correctness of the control strategy are verified by experimental r |
