This paper proposes an advanced state of function (SOF) estimation algorithm to determine the cranking capability of starting lighting ignition (SLI) battery. This algorithm defines the cranking resistance describing the voltage drop right after the time of cranking. And in order to increase the estimation accuracy against the effect of unpredictable battery parameter changes, a process of online...
In this paper, a hybrid control of IPT system is proposed in limited operating frequency range according to coupling coefficients. The coupling coefficient k and self-inductance of pad vary according to misalignment and vertical distance condition in inductive power transfer (IPT) system. Those variation cause change of output voltage and zero phase angle (ZPA) frequency. Proposed method enables the...
This paper presents a grid-connected PV-PCS (photovoltaic power conditioning system) using interleaved, soft switching boost converter for efficiency increment. The numerical analysis about power loss on the proposed PV-PCS is performed. And this analysis is confirmed by the simulation results. It is expected that the analyzed results can be used in the efficiency improvement of PV-PCS.
The paper proposes a new topology for photovoltaic DC/DC converter with high efficiency under wide input voltage range is proposed. Photovoltaic DC/DC is a very crucial part of power conditioning system(PCS). Considering that output characteristic of photovoltaic cell has wide voltage range, depending on the operating conditions of photovoltaic cell, the DC/DC converter also needs to have wide input...
