摘要: Active front-end (AFE) rectifiers are becoming widely used in medium-to-high-power adjustable speed drives (ASDs) to achieve regenerative operation and meet the energy efficiency harmonic requirements. The typical control methods with AFE include voltage-oriented (VOC), direct power (DPC) virtual-flux-based methods. This paper presents a dynamic average-value model (AVM) of rectifier system which is based on voltage-source converter (VSC) operated DPC. developed AVM modeling methodology presented this highlight specifics hysteresis bang-bang type DPC that track real reactive references. proposed demonstrated significantly reduce computing effort while accurately capturing fast transient performance system.
