Switches for DC converter functionality and reverse polarity protection functionality

摘要

In some embodiments, circuitry (101) is provided. The circuit can include the following: an interface (111) which is designed to connect the circuit (101) to a power supply unit, a power stage (119) which is designed to connect the circuit (101) to an electric drive, operable in an engine mode and a generator mode, at least one switch (112) connected between the interface (111) and the power stage (119), and control circuitry configured to switch the at least one switch (112) in operate in a first mode or in a second mode depending on whether the electric drive is operating in the motor mode or in the generator mode, the at least one switch (112) being designed, when operated in the first mode, with respect to a DC converter functionality to provide a DC voltage (162) at the power stage (119), and wherein the at least one switch (112) is designed when it is in the z wide mode is operated to provide reverse polarity protection functionality in relation to a supply voltage (161) received from the power supply unit via the interface (111).
