In this study, a high voltage-boosting converter is presented, which combines a coupled inductor, a charge pump capacitor, and active clamp circuit, so as to boost up the output voltage as well as to make the main switch turned on with zero voltage switching. In this converter, the coupled inductor behaves as not only an inductor but also a transformer. And, the active clamp switch in the active clamp...
Dual-buck circuit has higher reliability as it overcomes the straight-leg problem existing in the traditional bridge circuit. However, more magnetic components are needed in this topology, especially in three-phase dual buck inverter. Magnetic integration is a good way to reduce the volume and weight of the magnetic components and improve the density of the system. The coupled-inductor dual-buck circuit...
To cope with power from large-scale renewable systems, more and more power electronic converters are used in parallel. Typically, carrier interleaving is used, thus leading to a decrease in filtering requirements. However, this causes additional circulating current to flow between the modules of the converter. The modules of the parallel converters are Voltage Source Converters (VSC). Usually, a coupled...
