An LLC resonant power regulator system (10) includes a transformer (22) comprising a primary inductor (20) and a secondary inductor (26) and an input resonant tank (18) comprising an input resonant capacitor, an input leakage inductor, and the primary inductor (20) connected in series. The system also includes an input stage (14) comprising a plurality of switches (16) that are controlled in response to a respective plurality of switching signals sweeping frequency to supply an input resonant current to the input resonant tank (18). Each of the respective plurality of switching signals can have a fixed duty cycle and a sweeping frequency. The system (10) further comprises an output resonant tank (24) comprising an output resonant capacitor, an output leakage inductor, and the secondary inductor (26) connected in series. The output resonant tank (24) can be configured to generate an oscillating output resonant current at an output. |
