This paper presents the development of a wind Interior Permanent-Magnet Synchronous Generator (IPMSG) based bipolar DC microgrids along with various switch-mode rectifiers. Firstly, the wind IPMSG is established and adequately controlled to possess satisfactory generating characteristics during different driven speeds and loads. Later, the boost switch-mode rectifier (SMR) based bipolar DC bus is established. Further, three-phase single-switch (3P1SW) boost SMR, three-phase two-switch (3P2SW) three-level boost SMR, and a three-phase three-switch (3P3SW) Vienna SMR are comparatively evaluated. Along with the proposed robust voltage and current controls, a well-regulated microgrid DC-bus voltage is established. Moreover, the voltage balancing control is proposed to minimize the imbalance in the bipolar DC-bus voltage. For the wind IPMSG having Vienna SMR, the commutation angle setting is adjusted to use the reluctance power component effectively.

Power Electronic Converter

Although apparently simpler, the SRM drives are nowadays more expensive than their conventional AC drive counterparts. This is to a great extent caused by the lack of a standardised power electronic converter for SRM drives, which would be available on the market as a single module. A number of attempts were therefore made in recent times to develop novel power electronic converter structures for SRM drives, based on the utilization of a three-phase voltage source inverter (VSI), which is readily available as a single module. This paper follows this line of thought and presents a novel power electronic converter topology for SRM drives, which is entirely based on utilization of standard inverter legs. One of its most important feature is that both magnetizing and demagnetizing voltage may reach the DC-bus voltage level while being contemporarily applied during the conduction overlap in the SRM adjacent phases. At the same time, the voltage stress across the power switches equals the DC-bus voltage. The topology is functional in all operating regimes of the drive. Principle of operation is explained in detail for a three-phase SRM drive and experimental results obtained with a 6/4 switched reluctance motor, are included. Four inverter legs are required in this case. Some considerations, justifying the proposed converter topology from the point of view of the cost, are included.
