Apparatus For Increasing An Input Voltage For An Electric Vehicle, Electric Vehicle And Method For Operating An Apparatus

An apparatus for increasing an input voltage for an electric vehicle has an energy supply interface to a vehicle battery, a DC-DC converter and an inverter. The DC-DC converter has a first connection for connection to the energy supply interface and a second connection for connection to the inverter. The DC-DC converter is designed to supply an output voltage at the second connection in response to an amplifier signal, the output voltage being increased with respect to an input voltage applied to the first connection. The inverter has an inverter connection for connecting the inverter to the second connection and has at least one energization interface for energizing at least one unit coupled to the energization interface, the inverter converts a DC voltage applied to the inverter connection to an AC voltage and to supply same to the energization interface.
