Ten-Phase-Nine-Leg Topology for Five-Axis Active Magnetic Bearing Drive
Active magnetic bearing plays an essential role in high-speed rotational machine. Due to the need for multiple coils, optimal control performance necessitates power amplifier with numerous power electronics switches. However, a significant amount of power electronics switches greatly increases cost, volume and risk of switch failure. Therefore, this paper proposes a novel topology for optimizing the number of switches without affecting control performance. The basic properties and control strategies of the Ten-Phase-Nine-Leg topology are analyzed in Section 2. In simulation, results proved the feasibility of this topology, shown in Section 3. Finally, Section 4 concludes this article.
