Abstract
Conventional electric motor emulator (EME) systems usually employ two-level inverters as their power stage circuit, which face increased voltage stress, higher switching losses, and degraded current performance when operated at higher speed and voltage. To address these challenges, adopting multilevel inverter topologies has been proposed in various power electronic applications. Nevertheless, increased power device count and cost are usually considered drawbacks of multilevel structures. Among these, the hybrid active neutral-point clamped (H-ANPC) three-level inverter has been extensively studied for its potential to reduce voltage stress and improve efficiency. Despite its advantages, no existing literature has explored the use of HANPC topology as the power stage of an EME system. Therefore, this paper proposes an EME using an H-ANPC three-level inverter to mitigate these challenges. Simulation and experimental results validate the feasibility of integrating this topology into EME systems, providing a practical reference for future highvoltage or high-speed emulation applications.
