PHIL

Power hardware in the loop (PHiL) is a variant of the original HiL concept. The HIL concept is retained and is supplemented with extra power - read amplifier - in the loop. In this way, the HIL concept is made suitable for controlling physical components or subsystems that require more power. This includes testing or designing electric motors, transformers or inverters. In a PHIL system, the equipment to be tested (e.g. an inverter) is integrated into a test setup with real-time simulation models of other equipment and systems (e.g. an electricity network or a wind turbine). ). The whole is then controlled by a real-time simulation environment that coordinates and controls the behavior of the entire setup. PHIL offers several advantages over conventional testing systems, including a higher degree of safety, accuracy, reproducibility and flexibility. It also makes it possible to perform the most advanced and complex test scenarios that are difficult to achieve with traditional testing methods.
