This paper deals with comparative analysis different control methods of the Z-source inverter (ZSI). These control methods are Simple boost control SBC, maximum boost control MBC, maximum constant boost control MCBC, and the space vector modulation SVM. The relationship of voltage gains to modulation index and the THD are analyzed in detail and verified by simulation for the same modulation index.
This paper presents Direct Power Control (DPC) based on instantaneous power theory is presented. The simulation of a grid connected five level inverter via an inductive filter with a new direct power strategy is used. However, this control method is similar to the classic DPC method, in which used triangles instead of the sectors. Furthermore, the regulation of DC link without interfering the hysteresis...
This paper concentrates on the control of power flow in single stage photovoltaic energy conversion system. The conversion structure has a twofold requirement that consists in ensuring that the current injected to both load and grid obeys to the grid connection standards and sets the DC bus voltage similar to the reference voltage given by the MPPT algorithm. The advanced functions that can be added...
