Power Conversion in Renewable Energy Systems
Electricity generated from natural sources such as sunlight and wind varies over time and cannot be fed directly into the power grid. IGBT power semiconductors sit at the core of power conversion systems, shaping electricity into the stable form required for grid integration. As the global transition toward sustainable energy accelerates, the demand for high-efficiency power conversion technology continues to grow.
SwissSEM offers a portfolio of IGBT and SiC MOSFET products designed to help renewable energy systems achieve high power output with reduced losses. These modules serve solar inverters, energy storage converters, and wind power applications.
Key Applications in Renewable Energy
1500V Centralized Photovoltaic Inverters
The i23 series IGBT modules deliver low saturation voltage (VCE(sat) = 1.55V at 900A, 25°C) and optimized switching performance for high-power solar inverters. This low conduction loss directly translates to improved energy harvest from photovoltaic arrays.
Centralized Energy Storage Converters
With d23 diode technology featuring soft recovery design, these modules ensure safe reverse recovery for three-level energy storage systems. The optimized FRD offers 0.25V lower VF compared to the previous generation, specifically tuned for energy storage power conversion systems.
Wind Power Converters
The 1700V and 2300V IGBT chip series provide the robustness and reliability needed for wind energy environments. These voltage classes support the demanding requirements of wind turbine power electronics.
UPS Systems
ED-type and ST-type modules offer the current density and thermal performance required for uninterruptible power supplies in renewable energy installations.
