Leading products for end-to-end solar power solutions
One of the biggest challenges facing the renewable sector is the need to balance supply and demand. The power supplied by photovoltaic (PV) modules fluctuates heavily depending on weather conditions.
PV modules supply power in the form of direct current (DC). This has to be converted to alternating current (AC) before it can be fed into the grid and be either consumed locally or transmitted to the point of use. Solar inverters convert DC to AC.
Combining solar panels with energy storage systems is one effective way of synchronizing supply and demand. Efficient and reliable power semiconductors and inverter technologies are required to convert DC to AC and transmit the power with minimal losses. Depending on their implementation topologies, inverters fall into the micro-inverter, power optimizer, string inverter or central inverter categories.

With CoolSiC™ MOSFETs, the power of a string inverter can be doubled at the same inverter weight. CoolSiC™ allows a power density increase by a factor of 2.5, e.g. from 50 kW (Si) to 125 kW (SiC) at a weight of less than 80 kg, so it can be lifted by two installers. Furthermore, the efficiency reduction at high operating temperatures is significantly lower compared to a Si solution. You can achieve a maximum efficiency of over 99% by using CoolSiC™ MOSFET solutions from Infineon.
