Partial shading on a photovoltaic (PV) module consisting of multiple cells is known to trigger significant reduction in power yield and occurrence of multiple maximum power points (MPPs). Various kinds of voltage equalizers have been proposed to address these issues. This paper proposes a novel voltage equalizer utilizing diffusion capacitance, a parasitic element of PV cells, to drastically reduce capacitor count in a circuit. Furthermore, a novel MPP tracking (MPPT) technique is also proposed to realize the optimal operation of the proposed equalizer. Experimental verifications were performed using actual PV cells, demonstrating the efficacy of the proposed equalizer and its MPPT technique. |
