Abstract: This paper presents a new single-stage, single-phase SPV based, grid connected dc-ac boost converter with an active power injection and reactive power compensation scheme. The single stage topology consists of a full-bridge dc-ac inverter, but uses a single circuit for boost operation and dc-ac inversion. The sinusoidal output voltage is obtained by utilizing a variable duty cycle. A current based perturb and observe control algorithm is used for tracking the maximum power point of the solar panel. The active power is injected from the SPV panel and the reactive power is compensated by extracting the load current.
