zero ripple half bridge configuration using a tapped inductor approach as illustrated the tapped inductor embodiment involves combining the number of turns that are equivalent between the primary and secondary windings thus as illustrated the embodiment comprises one inductor l 1e with three pins 910 902 and 903 pin 903 at the first end of the inductor l 1e is coupled to switching node 201 pin 901 at the other end of inductor l 1e is coupled to one end of main output capacitor c 1 the auxiliary output is tapped from pin 902 and coupled to inductor l 2 and auxiliary output capacitor c 2 the principle of the tapped inductor configuration may be explained using the coupled inductor embodiment of fig7 for example if the number of turns in the primary windings e g n p of the coupled inductor 710 is thirty and the number of turns in the secondary windings is twenty four e g n s then the number of equivalent turns is twenty four using the above example in embodiments that employ the tapped inductor configuration the main inductor l 1e referring to fig9 will have thirty turns between pins 901 and 903 a secondary tap is included at pin 902 which is located between pins 901 and 903 to represent the number of turns of the secondary winding of l 1c in the current example the tap at pin 902 is located such that there is twenty four turns between pins 902 and 903 thus instead of the two windings of the embodiment illustrated in fig7 only one tapped winding may be utilized to magnetically achieve the same result fig1 is an illustration of the full bridge version of the tapped inductor embodiment to ripple steering as illustrated the full bridge version involves.
