Snubber Circuits Suppress Voltage Transient Spikes in Multiple
Output DC-DC Flyback Converter Power Supplies

Abstract: The flyback dc-dc converter topology results in significant cost and space savings for multiple output
power supplies with high output voltage for power levels up to 100W. Flyback topologies store and transfer
energy using a transformer, which due to physical limitations can cause large voltage transient spikes during
the
