Abstract
The invention relates to a power source () for providing a direct current, comprising a heavy-current transformer () with at least one primary winding () and at least one secondary winding () with center tapping, a synchronous rectifier () connected with the at least one secondary winding () of the heavy-current transformer () and comprising circuit elements (), and a circuit () for actuating the circuit elements () of the synchronous rectifier (), and a supply circuit () for supplying the synchronous rectifier () and the actuation circuit (), and to a method for cooling such a power source (). For reduction of losses and improvement of efficiency, the synchronous rectifier () and the actuation circuit () and the supply circuit () thereof are integrated in the heavy-current transformer ().
