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 19):
A power conversion device connected to a power source and a load, comprising:\n a first switching device configured to selectively allow power from the power source to communicate with the load in a first state thereof, and not allow power from the power source to communicate with the load in a second state thereof; a control circuit connected to the first switching device to communicate therewith to select the first state or the second state; a startup circuit interposed between the power source and the control circuit, the startup circuit comprising an isolation circuit and a current source circuit, the isolation circuit including a first current path and a second current path that includes a phototransistor or a relay switch, current flowing through the phototransistor or the relay switch causing current flow in the first current path; and an auxiliary circuit interposed between the power source and the control circuit, wherein the startup circuit is configured to supply a current to the control circuit as a result of the current flow through the first current path when the auxiliary circuit is not supplying current to the control circuit, and, to prevent current flow therethrough when not supplying current to the control circuit.
