Abstract
This paper presents a high efficiency photovoltaic (PV) panel integrated power conditioning system (PCS) by proposing a high efficiency step-up DC-DC converter. The suggested PCS consists of a high efficiency DC-DC converter and a single-phase DC-AC inverter. Each PV panel has its own DC-AC converter, performing the maximum power point tracking (MPPT) function and increasing its flexibility and expandability. Moreover, the proposed DC-DC converter converts the low PV panel voltage into a high DC-link voltage with a high step-up voltage conversion ratio. It can reduce the switching power losses, increasing the power conversion efficiency. The performance of the suggested PCS has been verified through a 180 W prototype of the PCS for a 60 Hz/120 V ac power grid. The proposed DC-DC converter achieves a high efficiency of 96.0%. The PCS including the DC-DC converter and DC-AC inverter achieves an efficiency of 93.1% with an almost unity power factor.
