The feature is aimed at Full Power Inverter Testing. You can load a virtual description of a machine, test your inverter hardware and software, then change the motor in software to test it again. It offers the advantages of a full power test, but with the flexibility of modelling.
The E-Motor Emulator combines hardware in the loop (HIL) technology to achieve fast dynamic response, high accuracy, low power consumption, low cost and high flexibility.
Traditional testing methods require a motor testing platform that includes a real-time simulator and a power amplifier. This method has power limitations, large loss, and poor flexibility, and cannot fully verify the function of the Device Under Test (DUT).
BriPower’s -EME option can accurately control the load on the three-phase output of the motor controller by solving dynamic mathematical models of machines like permanent magnet synchronous motors (PMSM) and asynchronous motors (ASM). The –EME can be programmed to create fault scenarios repeatedly that could be very difficult to achieve on a real motor/dyno set up. It can also be used to create parameter sweeps to verify a controller design will work well with real life issues like manufacturing tolerances or degradation.
Parameters
The KGS series E-motor emulator has a switching frequency of 120 kHz, fast dynamic response, and high simulation quality. It can apply accurate voltage at the DUT dynamically and can monitor the model parameters in real-time by modifying the motor parameters.
The KGS series E-motor emulator includes multiple output power levels from 45 KVA to 540 KVA. In the frequency range of DC~2000 Hz, the maximum output voltage of 750 VL-N.
