This paper presents a multifunctional interface circuit for the battery-ultracapacitor hybrid energy storage system (HESS). Both the voltage equalization of the battery banks and energy exchanging between two kinds of energy source will be realized, by using the appropriate control strategy. Thus the reliable work and the health of the battery bank can be maintained, and the ultracapacitor (UC) can...
The performance of phase-locked loop (PLL) severely affects the system's stability in a three-phase rectifier. Traditional methods tend to adopt the idea of single synchronous coordinate transformation, which implements the phase synchronization through controlling the q-axis voltage to zero. A novel three-phase PLL is proposed in this paper based on this idea. In order to obtain better convergence...
In this paper, a current controller based on equivalent-input-disturbance (EID) approach for the grid-connected single-phase photovoltaic inverter in microgrid is proposed. First, a signal generator is employed to generate the amplitude and the phase of reference current. The amplitude is calculated according to the data obtained from experiment devices, while the phase is regulated by a phase-locked...
