This paper considers a single-phase grid-connected converter in the presence of non-linear loads. A local voltage support strategy is proposed to compensate the harmonics caused by the loads. This is an added feature implemented in parallel with a conventional current control method, and distinctively, it does not need measurements of the grid or load current. The converter output current consists...
This paper proposes a four-degree-of-freedom control method for a dual active Flexbattery H-Bridge converter, which operates similarly to dual-active- bridge converters. The Flexbattery pack is constructed from multiple modular units and each unit contains one voltage source, one inductor and four switches. Due to the cascaded structure of the pack, it is able to generate high-frequency square-waveform...
Critical Conduction Mode (CRM) Flyback APFCs is widely used in High Brightness Light Emitting Diodes (HB-LEDs) driver. But with high input voltage or light load, its line current distortion deteriorates because of the peak distortion. In this paper, an improved control strategy is introduced to solve this problem. It is realized by the injection of sin2θ component to primary reference current. Nonetheless,...
With high input voltage or light load, the peak of AC line current for critical conduction mode (CRM) flyback power factor Correctors (PFCs) appears notably distorted. In this paper, the reasons of line current distortion are investigated. Moreover, the relationship between line current peak distortion and high input voltage or light load is presented. Based on theoretical analysis, a simple improved...
