a method for providing non - resonant zero - current switching in a switching power converter operating in a continuous current mode . the switching power converter converts power from input power to output power . the switching power converter includes a main switch connected to a main inductor , wherein an auxiliary inductor is connectible with the main inductor . the main current flows from an input to an output . the auxiliary inductor is connected with the main inductor thereby charging the auxiliary inductor so that an auxiliary current flows from the output to the input opposing the main current . upon a total current including a sum of the main current and the auxiliary current . substantially equals or approaches zero , the switch is turned on .
