介绍了用于开关磁阻电机的集成分布式逆变器的概念。目前的应用是专为铁路牵引应用而设计的外转子直接驱动。开发了五相开关磁阻电机，并用于演示集成分布式逆变器的功能。通过为每个相线圈提供自己的模块化逆变器来实现配电。每个逆变器模块均均匀地放置在定子堆的末端，靠近其专用线圈。这显着增加了驱动器的冗余。由于不需要重叠的端匝，因此减少了相间故障的可能性。此外，机器和逆变器的集成也被简化，因为半导体可以均匀地分布在机器周围。该概念减少了驱动器和车辆之间用于通信、供电和冷却的端子数量，而与机器相数无关。通过集成和分布式逆变器，可以开发新的控制策略来影响机器振动和辐射噪声。本文分析了原型设计、五相电机的直接扭矩控制以及模块内部故障情况下的行为。
A concept of an integrated and distributed inverter for switched reluctance machines is introduced. The application at hand is an outer-rotor direct drive designed for railway traction applications. A five-phase switched reluctance machine was developed and is used to demonstrate the function of the integrated and distributed inverter. The distribution is achieved by supplying each phase coil with its own modular inverter. Each inverter module is placed evenly around the end of the stator stack next to its dedicated coil. This increases the redundancy of the drive significantly. The likelihood of phase-to-phase faults is reduced, because no overlapping end-turns are necessary. Also, the integration of machine and inverter is simplified, because the semiconductors can be evenly distributed around the machine. The concept reduces the amount of terminals between drive and vehicle to communication, power supply, and cooling, independent of the number of machine phases. With the integrated and distributed inverter new control strategies can be developed to influence machine vibration and radiated noise. In this paper, the design of the prototype, the direct torque control of the five-phase machine, and the behavior in the case of a fault inside a module is analyzed.
