SUPPLY CIRCUIT

A supply circuit providing transmission of a control signal to gate leg by a power transistor. The supply circuit includes a primary transistor, a primary resistance connected between the primary transistor drain leg and ground; a secondary resistant connected to supply leg of primary transistor on one side and to gate leg, the primary transistor and a power supply from other side; a secondary transistor connected to drain leg of primary transistor from gate leg, connected to ground from drain leg and connected to the power supply by means of a third resistance from supply leg and a control signal output connected to the secondary transistor supply leg, providing transmission of a control signal by power transistor to a gate leg.
