A novel Method of Power Inductor Measurement based on Half-bridge Circuit

Traditional methods of inductance measurement encounter difficulties when they deal with inductors working in both high frequency and high current.A novel method of inductance measurement based on half-bridge circuit is proposed, which can meet the requirement on megnetizing current,which include ac component,dc component and variable frequen- cy.In addition,the dynamic magnetization process of the inductor core can also be taken into consideration.Therefore,a much more accurate inductance result can be achieved.
