Abstract
A startup circuit for starting a power converter for converting an input voltage to an output voltage includes a switch connected in series with a resistive element. The startup circuit is connected in parallel with a trigger switch in the power converter for enabling the power converter to generate the output voltage. When closed or activated, the switch in the startup circuit charges an energy storing device in the power converter. The energy storing device activates the trigger switch as the charge is released.
