For inductors, such as DC chokes, PFC inductors, resonant inductors and fly-back transformers, magnetic field distributions in winding windows are extremely complex due to the air-gap fringing effects in the core. Existing high-frequency winding loss calculation method usually ignores the fringing effect losses caused by air-gap fringing fluxes, resulting much errors for winding loss analysis and...
In power system, the voltage pulsation and deficiency or surplus of reactive power will have a great effect on the quality of electric power supply. Through the appropriate and effective way of compensation, we can keep the balance of reactive power in the maximum degree by the maintenance of acceptable voltage. That's to say, quality of power supply can be improved greatly by the synthetic compensation...
In power system, the voltage pulsation and deficiency or surplus of reactive power will have a great effect on the quality of electric power supply. Dynamicly local reactive power compensation is one of the best methods to reduce the power network loss and improve the efficiency of transmission and distribution. Through the effective methods of compensation, we can keep the balance of reactive power...
