Abstract: A method for providing non-resonant zero-current switching in a switching power converter (30) operating in a continuous current mode. The switching power converter (30) converts power from input power to output power. The switching power converter (30) includes a main switch (Q1) connected to a main inductor (106), wherein an auxiliary inductor (302) is connectible with the main inductor (106). The main current (IP) flows from an input to an output. The auxiliary inductor (302) is connected with the main inductor (106) thereby charging the auxiliary inductor (302) so that an auxiliary current (Iaux) flows from the output to the input opposing the main current (IP). Upon a total current including a sum of the main current (IP) and the auxiliary current (Iaux), substantially equals or approaches zero, the switch (Q1) is turned on.

Abstract: A method for providing non-resonant zero-voltage switching in a switching power converter (42, 44). The switching power converter converts power from input power to output power during multiple periodic switching cycles. The switching power converter includes a switch (Qbu, Qbo) and an auxiliary capacitor (Cbu, Cbo) adapted for connecting in parallel with the switch (Qbu, Qbo), and an inductor (206) connectible to the auxiliary capacitor (Cbu, Cbo). The main switch (Q1, Q3) is on. A previously charged (or previously discharged) auxiliary capacitor (Cbu, Cbo) is connected across the main switch (Q1, Q3) with auxiliary switches (Qabu, Qbu, Qabo, Qbo). The main switch (Q1, Q3) is switched off with zero voltage while discharging/charging the auxiliary capacitor (Cbu, Cbo) by providing a current path to the inductor (206). The auxiliary capacitor (Cbu, Cbo) is disconnected from the switch (Q1, Q3). The voltage of the auxiliary capacitor (Cbo, Cbu) is charged and discharged alternatively during subsequent switching cycles. The voltage of the auxiliary capacitor (Cbu, Cbo) stays substantially the same until the subsequent turn off of the main switch (Q1, Q3) during the next switching cycle with substantially no energy loss in the auxiliary capacitor (Cbu, Cbo).
