Description
Summary:This study presents a simple design and cost-effective rectifier topology based on five-level multiple-pole structure. Better efficiency and low grid current total harmonic distortion is achieved with the constant low switching frequency operation. The proposed rectifier topology consists two set of VIENNA rectifiers to form a five-level input characteristic which is known as five-level/multiple-pole multilevel unity power rectifier (5L-M2UPFR). Observer techniques are designed for the proposed in-phase quantities carrier-based average current control scheme for the rectifier. Hence, unity power and input current shaping is achieved with the reduced sensor measurements. In addition to that, a proportional+resonance controller is implemented in the grid voltage observer to achieve dynamic response and better tracking under unbalanced grid condition.
