I would like to know the mechanism of occurrence of LC resonance during discontinuous operation of a diode-rectifying DC/DC converter.
- When the output capacitor is charged with electric charge, a current attempts to return to the diode side, but because current does not flow from cathode to anode, charge with nowhere to go causes resonance due to the parasitic capacitance components of the capacitors and diodes and the output inductor.
