High voltage DC/DC Converter with master/slave buck output stages

摘要

The present document relates to DC (Direct Current)/ DC converters. In particular, the present document relates to DC/DC converters with a modular structure for providing different levels of output currents. A power converter (300) configured to convert electrical power at an input voltage (111) into electrical power at an output voltage (112) is described. The power converter (300) comprises a first inverter stage (310) with a first half bridge comprising a first high side switch (101) and a first low side switch (102) which are arranged in series between the input voltage (111) and a reference voltage; and with a first high side driver (121) for providing a first drive signal for the first high side switch (101), subject to a high side control signal at a drive voltage level. Furthermore, the power converter (300) comprises a second inverter stage (320) with a second half bridge comprising a second high side switch (101) and a second low side switch (102) which are arranged in series between the input voltage (111) and the reference voltage; and with a second high side driver (121) for providing a second drive signal for the second high side switch (101), subject to the high side control signal at the drive voltage level. In addition, the power converter (300) comprises a level shifting unit (211) 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 first and second high side switches (101).
