Abstract

The two-level single-ended primary-inductor converter (SEPIC) has been used for grid-tied photovoltaic (PV) systems. However, it has high switching losses because of high voltage stresses. To reduce the switching losses, a three-level SEPIC is suggested in this paper. The three-level SEPIC has low switching losses by reducing the switch voltage stress. It improves power efficiency by using a lower-voltage-rated switch compared to the switch in the two-level SEPIC. The capacitor voltage balance control is presented with a maximum power point tracking (MPPT). Experimental results for a 1.0 kW prototype system are discussed with a grid-tied transformerless H6 inverter.
