Abstract
The present document relates to DC/DC converters with a modular structure for providing different levels of output currents. A power converter configured to convert electrical power at an input voltage into electrical power at an output voltage is described. The power converter comprises inverter stages with half bridges comprising a high side switches and low side switches which are arranged in series between the input voltage and a reference voltage; and with high side drivers for providing drive signals for the high side switches, subject to a high side control signals at a drive voltage level. In addition, the power converter comprises a level shifting unit configured to convert a high side control signal at a logic voltage level into the high side control signal at the drive voltage level for driving the high side switches.
