摘要：

In　this　paper,　a　super　capacitor　charging　management　integrated　circuit　(IC)　based　on　reconfigurable　photovoltaic　cells　array　is　proposed.　This　IC　is　based　on　a　novel　maximum　power　point　tracking　(MPPT)　method　that　arranges　photovoltaic　(PV)　cells　into　different　combination　networks　in　order　to　optimize　the　charging　efficiency　dynamically.　With　the　reconfigurable　PV　array,　various　voltage　outputs　of　PV　cells　charge　the　super　capacitor　without　inductor　based　switching　regulator.　The　MPPT　circuit　is　designed　according　to　the　I-V　characteristics　and　P-V　characteristics　of　the　PV　cells.　Depending　on　the　charging　stage　of　the　super　capacitor,　different　series/parallel　combination　networks　of　the　PV　cells　are　selected　to　make　the　PV　cells　work　in　the　vicinity　of　the　maximum　output　power　to　achieve　a　higher　charging　efficiency.　Charging　current　of　a　single　PV　ranges　from　10μA　to　100μA,　the　charging　efficiency　from　a　small　PV　cells　array　to　IF-5V　super　capacitor　can　reach　more　than　80%,　up　to　94%.　©　2018　IEEE.
