Abstract
A photovoltaic powered system and an alternating current (AC) module thereof are disclosed. The photovoltaic powered system provides a direct current (DC) power through a photovoltaic module and converts the DC power into an AC power, which is grid-connected to an AC utility power. The AC module of the photovoltaic powered system produces a continuous quasi-sinusoidal current and the quasi-sinusoidal current is converted into a sinusoidal current. The high-frequency harmonic components of the sinusoidal current are filtered to produce a sinusoidal output current in phase with the AC utility power, thus realizing the maximum power point tracking (MPPT) of the photovoltaic module and feeding unity-power-factor power into the AC utility power.
