Circuit and Method to Suppress the Parasitic Resonance from a Dc/dc Converter

A snubber circuit for use with a DC/DC converter broadly comprises a snubber resistor connected in parallel with a snubber inductor. The DC/DC converter may include a voltage source, a first switching element, a second switching element, an output inductor, and an output capacitor. The voltage source may include a positive terminal and a negative terminal connected to a ground node. The first switching element may include a first terminal connected to the positive terminal of the voltage source The second switching element may be connected to a second terminal of the first switching element. The series combination of the output inductor and the output capacitor may be connected between the second terminal of the first switching element and the ground node. The snubber circuit may be connected between the second switching element and the ground node.
