Control architecture for Spar Engineering's next generation Variable Frequency Drives

近年来，由于变频驱动器（VFD）装置的优点， 它们在实现节能运行方面提供的经济优势。因此，VFD不可或缺 泵、压缩机、冷却器、风扇、鼓风机、破碎机等许多工业应用的零部件， 传送带SPAR Engineering作为支持机构提供咨询和设计工程 服务于电气，控制和自动化领域，在各个行业，如采矿，公用事业，石油和 天然气、纸浆和纸张、能源和水/废物管理。 随着新的微控制器和控制VFD的新兴方法的出现，该公司处于 改进以前的设计并提供下一代VFD的过程。所要求的资金是 使SFU的研究人员能够与该公司密切合作，开发其下一代VFD装置。的 目前的驱动器可以在六脉冲和十二脉冲非再生模式下操作 嵌入式控制技术此外，为了获得竞争优势，公司希望实施 控制算法的最新进展融入新产品。这就需要新型的微处理器， 比目前使用的高得多的密度和完全不同的架构。

There has been widespread use of Variable Frequency Drives (VFD) devices in recent years due to the economic advantages they offer in achieving energy-efficient operation. As a result, VFDs are indispensable components of many industry applications such as pumps, compressors, chillers, fans, blowers, crushers, and conveyors. The supporting organization, SPAR Engineering provides consulting and design engineering services in the areas of electrical, control, and automation, in various industries such as mining, utilities, oil and gas, pulp and paper, energy, and water/waste management. With the advent of new microcontrollers and emerging methods for controlling VFDs, the company is in the process of refining the previous designs and offering its next generation of VFDs. The requested funding is to enable the SFU researchers to work closely with the company to develop its next generation VFD unit. The present drive can operate in both six and twelve pulse non-regenerative modes but is using a relatively old embedded control technology. Furthermore, to have a competitive edge, the company wants to implement recent advances in control algorithms into the new product. This needs new breeds of microprocessors with much higher density and completely different architectures than what is currently being used.
