Direct voltage converter has device that selects first feedback regulation mode independently of load current in response to voltage level change, second mode if load current less than defined value

摘要

The device switches semiconducting switch elements on and off to deliver a direct voltage whose level is converted to a defined level to a load. A selection device (10) selects a first feedback regulation mode independently of a load current but in response to the level change of the direct voltage delivered to the load and a second mode in response to a load current less than a predefined value.
