Infineon Five-Level Active Neutral Point Clamped Flying Capacitor Inverter Design Based on Optimos 5 150V Flyback

The EVAL_4kVA_230VAC_5LINV 5-level active neutral-point-clamped flying capacitor (ANPC-FC) inverter evaluation board is based on 150 V OptiMOS™ 5, XMC4700 microcontroller and EiceDRIVER™ 2EDF7275F gate driver,featuring demonstrates ultra-high efficiency peaking at over 99%. It also provides>98.5% efficiency over a wide range of load with minimal power losses distributed among SMD MOSFETs. This enables operation at maximum load without heatsinking or the need for forced air cooling. The multi-level inverter is based on 150 V OptiMOS™ 5 technology, which has low RDS(on) and Qrr. This hybrid enables reduction in size and weight for solar inverters, string inverters and general purpose inverters.
