Direct current converter for battery charger of car, has electrical insulation positioned between microcontroller and power stage, and converting unit for providing conduction time of power stage, which is less than specific percent

摘要

The converter has a measuring unit for measuring voltage in a power stage. Another measuring unit measures current in the power stage. A control unit controls the power stage. An electrical insulation is positioned between a microcontroller and the power stage. A converting unit provides a conduction time of the power stage, which is less than 50 percent. The power stage comprises two flyback-type converting parts (8a, 8b) that are connected in a parallel manner. Each converter part is connected to a diode bridge (9).
