The auxiliary inverter controls the electric motors of electric power steering (EPS), HVAC control, water pumps, brake vacuum pumps, oil pumps, compressors, and other applications which are key components in cars. . An inverter converts direct current (DC) from batteries or fuel cells into alternating current (AC). This AC can operate AC equipment designed for standard outlets. Inverters also adjust output voltage and can perform rectification, changing AC back to DC for versatile energy use. The primary. . Infineon offers highly efficient and flexible inverter solutions for auxiliary systems in electric vehicles (EV). Our full automotive-qualified product portfolio supports a wide range of applications that are crucial to the operation of an electric vehicle, such as electric power steering (EPS). . At its heart, a battery inverter is an electronic device that transforms direct current (DC) electricity, typically stored in a battery, into alternating current (AC) electricity, the type used by most household appliances and electronic devices. This conversion is essential because batteries store. . Auxiliaries can be described as all the extra loads on a vehicle which do not contribute to traction power. On a combustion vehicle the engine drives these auxiliaries. Battery inverters play an irreplaceable role in renewable energy generation, energy storage systems, emergency power and other fields. In this article. . The function of the auxiliary inverter is to convert the DC power of the battery into AC power to supply the motor. It consists of an inverter bridge and control logic. The auxiliary inverter can provide various types of peripheral devices, such as air conditioning compressors, cooling fans. .
