In AC/DC converters for on-board chargers, the DC-link capacitor on the output side in a power factor correction (PFC) converter uses aluminum electrolytic capacitors in order to obtain a large capacitance with low voltage ripple and small size. Therefore, it is necessary to reduce the capacitance when using film capacitors without increasing the size of the converter in order to realize a capacitor...
Recently, the capacity of renewable power sources installed in small remote islands, whose power grid is isolated from large scale grid, increases because of the environmental affairs and the generation cost and so on. But in the small remote island grid, the power fluctuation caused by renewable power sources affects power grid stability and operation. In this paper, several stabilizing methods based...
A new control approach for bidirectional DC-DC (BDC) converter is proposed in this paper. This approach aims at controlling a BDC in such a way that makes it behaves like a multi-level virtual conductor. As a matter of fact, the voltage difference between the terminals of any conductor is zero volts. Conversely, the main target of the proposed control approach is to keep the voltage difference between...
