Abstract: Photovoltaic (PV) system is categorized as one of the renewable energies that have a great potential compared to its counterparts. An experimental model “Stand Alone Photovoltaic AC/DC Supply System” unit has been developed to understand the operational principle of photovoltaic system. In order to drive the AC appliances; inverter circuit is added to this unit to invert the direct current (DC) battery voltage to the alternative current (AC) at 240V, 50Hz. Chosen topology of this inverter is “chop and transform” and output waveform is square wave. The paper is an attempt to understand the working principle of this inverter circuit by analyzing the output waveform of the circuit's main components.

Key words: photovoltaic system, inverter circuit
