Leading products for end-to-end solar power solutions
Photovoltaic systems are one of the most demanded applications to address carbon reduction and increase the share of renewable energy in the grid. However, 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. Nevertheless, the challenge of quitting fossil energy sources can be achieved with smart grid management and an energy storage system. PV panels supply power in the form of direct current (DC), which has to be converted to alternating current (AC) before it can be fed into the grid and consumed locally or transmitted to the point of use. Solar inverters convert DC to AC.
Efficient and reliable power semiconductors and inverter technologies are required to convert DC to AC and transmit the power with minimal losses. Combining solar systems with energy storage systems is one effective way of synchronizing supply and demand. Depending on their implementation, inverters fall into the categories micro inverter, power optimizer, string inverter, hybrid inverter, and central inverter.

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 that two installers can lift it. With CoolSiC™ MOSFETs, the power of a string inverter can be doubled at the same inverter weight. Furthermore, the efficiency reduction at high operating temperatures is significantly lower compared to a Si solution. You can achieve maximum efficiency of over 99% by using CoolSiC™ MOSFET solutions from Infineon.
