In this paper it is presented a detailed descr iption

of the analog implementation of the control for a DC-AC

converter composed by a DC-DC Zeta converter and a low

frequency inverter. Using only analog components, it was

developed the MPPT technique based on linearization of solar

panel characteristic around the MPP, a feedforward control and

a robust PWM sine wave modulator. This simple and low cost

solution was designed to be used in grid connected rooftop

photovoltaic panels (PV). In scenery where an entire city area

could be used to generate extra power, reducing the necessity of

huge central power plants, module integrated inverters will play

an important role on grid connection of PV systems with high

reliability due to the high level of redundancy. The experimental

results show that this simple cost effective solution is able to

extract maximum power PVs with low current harmonic
