Microinverter solutions
Microinverters convert power at individual photovoltaic (PV) panels and are usually rated at below 400 Watt for single PV panels and up to 1.5 KW for multiple PV panels. Microinverters typically rely on two-stage power conversion.
First, booster or maximum power point tracking (MPPT) stage is used to boost and maximize the energy harvested from the PV panels. Then in the inverter stage, AC voltage is generated, that is compatible with single or three phase gird.
Contrary to string inverters that are connected to multiple panels in series and perform MPPT per string of PV panels, microinverters are attached to one, two or four PV-panels. That is why overall system energy yield with microinverters are more than string inverters.

Infineon’s Easy family’s tremendous growth in the past few years led Easy modules to become even more flexible and scalable in key areas, such as voltage class and topologies.
As a result, Easy modules are widely used, not only in industrial applications but also in automotive applications.
To continue the successful momentum created by Easy 3B, “the big brother of the family”, Infineon has successfully developed the Easy 4B package, extending the package’s capabilities even further!
The EasyPACK™ 4B is now the largest package in the Easy family, with three DCB substrates.
Let’s learn more about how solar inverters work, from the ones we have in our houses, to the ones that are applied in major factories. We will also see how Infineon innovates in power semiconductors for solar inverter technology and how that can help with reducing costs and time to market.
In this module, we will have a look at different solar inverter trends and how the technology is evolving.
And afterwards, we will see what Infineon’s comprehensive solutions for the positioning of solar applications are.
