Parallel/Series Connection of Self-Sustained Oscillating ...
In welding applications a series-parallel resonant converter is very advantageous since it enables to raise the output voltage for ignition, is short-circuit proof at the output, o ers soft switching condition and allows the possibility to utilise the transformer parasitics as resonant elements [8,9].
