  • Regulated blocking converter wherein switch conduction time increases with higher output voltages
    Patent number: 4924369
    Abstract: A feed circuit for feeding at least one user from an impressed direct current. In order to form a feed circuit for feeding at least one user with a dc voltage acquired from an impressed direct current in one stage and to thereby guarantee a power limitation, the feed circuit is formed as a blocking converter having a switch controllable such that the relative on-duration of the switch becomes increasingly longer for higher output voltages.
