Prototyping and Testing Power Electronics Systems Using Controller Hardware-In-the-Loop (HIL) and Power Hardware-In-the-Loop (PHIL) Simulations

Prototyping and proper testing of the electrical control unit of electric vehicles under various load profiles and fault conditions is necessary to ensure maximum efficiency of the electric motors, batteries and power electronics. Hardware-in-the-loop simulation and power hardware-in-the-loop offer means to prototype and test various controllers while simulating key parts of the system. This paper describes these two methods and presents results and design principles of a brushless DC motor emulation using PHIL simulation.
