Inverter Test for Electric Vehicles
Test benches for inverters in e-cars
Electric drive motors are controlled by inverters, which are designed as power electronics including control logic for electric motors.
Inverters convert the 3-phase alternating voltage of the generator (i.e. the electric motor during braking) into a DC voltage for charging the battery. Similarly, when the electric motor is driven, the DC voltage of the battery is converted into a 3-phase AC voltage.
Test benches for inverters are an elementary component of electromobility. Function tests, quality and endurance tests with or without environmental simulation (e.g. climate) as well as end-of-line test systems for different performance classes of inverters belong to the task spectrum.
