Let's now focus on the particular architecture of the photovoltaic inverters. There are a lot of different design choices made by. The first important area to note on the inverter after the input side is the maximum power point tracking (MPPT) converter. MPPT converters are DC/DC converters that have the specific purpose of maximizing the 1 power produced by the PV generator. Note. Next, we find the “core” of the inverter which is the conversion bridge itself. There are many types of conversion bridges, so I won't cover different bridge solutions, but focus instead on the bridge's general workings. In Figure 2, a three-phase inverter is. The most common method to achieve the MPPT algorithm's continuous hunting for the maximum power point is the “perturb and observe”.
