Abstract:
A power conversion device includes a power supply, transformer comprising a primary winding, a first secondary winding and a second secondary winding, a converter connected to the primary winding, a control circuit connected to the converter, and a startup circuit. The startup circuit comprises a first switching element configured to switch between an ON state and an OFF state, a constant current circuit configured to supply power of a predetermined voltage to the control circuit when the first switching element is in the ON state, and an isolator comprising a first current path connected to a control terminal of the first switching element, and a second current path isolated from the first current path and including a selectable connection to ground. The first switching element is switched to the ON state as a result of current flowing through the first current path when current flows in the second current path.

Claim (Index 2):
The power conversion device of  claim 1 , wherein the control circuit is configured to output a control signal to the converter to cause the converter to intermittently switch between an ON and OFF state to intermittently open a current path between the output of the power supply and ground, said current path including the primary winding of the transformer.
