Abstract :
A simple power conditioner to convert the power available from solar panels for feeding into 60 Hz AC mains is described. The output from the solar panels will be converted into a regulated DC voltage using a boost converter and a large capacitor. The DC output will then be converted to 60 Hz AC using a bridge inverter. The ratio between the load current and the short-circuit current of a PV panel at maximum power point is nearly constant for different insolation (light) levels and this property is utilized in designing a simple maximum power point tracking (MPPT) controller. The results obtained on an experimental converter are presented.
