Abstract :
An AC module is a PV module with an integrated DC/AC power converter which generates grid conforming AC power. In this paper, the ideas behind this portable and expandable AC PV power system are highlighted. The block diagram, the principle of operation and test results of a 130 W inverter are shown. The measurements show a power factor exceeding 0.99 at full load, whilst at 12 W partial load the power factor is better than 0.89. The harmonic distortion decreases from 8% at 30 W to 5% at 50 W and slightly decreases further at higher power levels. Previous measurements showed that an efficiency over 90% over a wide operation range is obtained. It is estimated that the cost price of the “touch safe” inverter (dimensions 100*100*20 mm), when produced in large quantities is between 0.5 and 1 $/Wp. The price performance ratio is obtained by application of resonant switching techniques enabling low component size and costs
