A new method is proposed for direct design of inductances in LC-type filters of rectifier circuits. This approach permits direct choice of the required core followed by unambiguous determination of the number of turns and the airgap length. This is done using the load voltage and current, the type of rectifier and the ripple of the rectified current specified by the designer.
