Micro-inverters and distributed maximum power point tracking (MPPT) solution as a PV dc ac converter market in the emerging field, is expected to grow significantly, from 2010 to 2015 the average annual compound growth rate of up to 77%.

     From the point of view of power systems, photovoltaic technology focuses on the following two aspects. First, from the perspective of photovoltaic systems, photovoltaic industry is one of the biggest challenges facing the shadow of the solar panel problems. Shadow changes, solar panels and panels of aging on the dirt, the voltage of the panels will be on impact, causing the output voltage in series with the panel changes.

Micro-inverter will be one alternative solution, it can achieve in the panel-level maximum power point tracking (MPPT), has the advantage beyond the central inverter. MPPT solar panels can be made ​​in each optimal power point, without the need for serial solar panels arranged in series, can minimize shadowing problems. The second is from the perspective of power devices, since the main PV system vendors have their own patent application PV inverter topology, semiconductor suppliers must develop specific products.

Therefore, these companies need to keep evolving solar inverter market emerging technology trends. For example, the need to increase the input voltage to achieve greater efficiency, it is necessary to use 650V or more MOSFET / IGBT. You might also want to use SiCSBD as a complete solution. In addition, to expand the market share of more than 10kW, you must use IGBT / SPM modules.

     For below 10kW grid-connected photovoltaic inverter solutions, Fairchild provides field stop (FS) IGBT and SupreMOSMOSFET devices have entered the market with the necessary high performance and high reliability low EOFF advantage. For micro-inverters, Fairchild has a medium-voltage MOSFET and SupreMOS technology to provide superior performance for such applications.
