【 摘 要 】

References(7)Cited-By(2)This paper presents a modified H-bridge seven-level single-phase grid-connected inverter for photovoltaic system with a novel pulse-width-modulated (PWM) control scheme. The inverter is capable of producing seven output-voltage levels (Vdc, 2Vdc/3, Vdc/3, 0, -Vdc, -2Vdc/3, -Vdc/3) from the dc supply voltage. Perturb and Observe (P&O) algorithm is used to extract maximum power from the PV module. MPPT and current control algorithm were implemented in an eZdsp board, TMS320F2812. The proposed system was implemented in a prototype.
