Development of a microcontroller-based inverter for photovoltaic application

Presented in this thesis is the development of a microcontroller-based inverter for photovoltaic systems. A single 8-bit microcontroller generated switching pulses for both stages of the inverter’s dc-dc converter and dc-ac inverter. A simple, effective algorithm suitable for implementation in a...
