The inverter is an intelligent mini-computer in electrified and electric vehicles. Together with battery and e-motor, they form the basis for the final driving experience. But, before all these components are tested together, every single one should be developed and validated on a dedicated test system. The frontloading of tests leads to shortened integration tests and therefore shorter time to market. The inverter controls and monitors all driving conditions and the vehicle’s safety-critical functionalities. Power electronics, in combination with a high level of signal complexity, require an appropriate test methodology and the use of adequate testing equipment.
The AVL Inverter TS™ enables independent testing of the inverter while optimizing the integration with all other components in the electrified powertrain. The test system is based on e-motor emulation technology with real-time simulation. This leads to highly accurate results when testing the inverter with required battery voltage and e-motor current. For such a testing setup, exact copies of the e-motor and the battery are required.
Within the AVL Inverter TS™, the e-motor is replaced very accurately with the Power Amplifier Cabinet (PAC) and the Signal Processing Cabinet (SPC). The UUT DC Supply Cabinet (USC) represents a digital copy of the battery. As a result, an efficient and flexible test equipment for the testing of inverters is available, which – in contrast to an active load cabinet – emulates with highest accuracy the real physics of an e-motor directly at the terminals.
The emulated e-motor must behave exactly like a real e-motor. Software tools are developed to ensure the optimal use of the test systems over their entire performance range and to render our specialist’s knowledge available for customers over a broad scope and without limitation. They make it possible to configure a machine model correctly and quickly, without the need for deep expert knowledge.
It is important to us to provide our customers not just with individual parts, but with a state-of-the-art, complete test system that is based on years of application know-how and thus enables our customers to use a highly efficient test methodology.”
