Electric machines emulators (EMEs) based on hardware-in-the-loop (HIL), which effectively act as emulators to mimic the actual motor behavior of Interior Permanent Magnet (IPM) machines. EME is frequently used to evaluate motor controller and motor control methodologies prior to development. The inverse magnetization motor model, which is used as the basis for real-time simulation in this paper’s proposal for an electric machine emulator system based on HIL, uses FEA to create the motor model data. The nonlinear features of the motor may be successfully replicated with this motor model, and the accuracy of the electric machine emulator can be enhanced by using a straightforward and trustworthy motor controller. The real-time simulation tool typhoon HIL is used in the study to develop a hardware-in-the-loop simulation platform for an IPM electric machines emulator.

A hardware-in-the-loop simulation test bench based on FPGA is proposed to efficiently solve the automotive power electronics testing technology. The test bench is composed of a master control system, a real-time simulation platform, an RCP rapid prototype controller, a tested controller and an OPAL-RT solver. The simulation step can reach 1us. Automated test software can be used to set test conditions and effectively verify the performance of MCU drive and fault protection strategies, demonstrating its effectiveness.

As a power hardware-in-the-loop (PHIL) technology, the power-stage motor emulator (ME) can be employed for the port characteristics emulation of motors. Meanwhile, the ripple current reproduction is one of the key technologies for achieving the high precision emulation of the port characteristics. Commonly, the high requirement for the hardware topology and the modulation strategy with rapid response and low harmonics are the main challenges. Aiming to obtain the precision ripple current, a ME scheme with dual-branch parallel topology is proposed in this paper, of which the equivalent switching frequency can be increased greatly by mean of interleaving switch. Furthermore, a new three-level space vector modulation strategy based on the idea of virtual transformation is presented. With the proposed strategy, the dual-branch parallel topology can be equivalently transformed into a specific three-phase three-level back-to-back topology. Finally, simulation and bench experiments have been conducted to validate the effectiveness of the proposed scheme. The results indicate that the proposed topology combined with the modulation strategy has a superior performance in improving the ripple current tracking accuracy of ME. Moreover, the proposed method can provide an excellent insight into improving the emulation accuracy of motor characteristics in practical applications.
