Reference design/demo board - 5-level flying capacitor active neutral-point-clamped inverter design
The EVAL_4kVA_230VAC_5LINV 5-level active neutral-point-clamped flying capacitor (ANPC-FC) inverter evaluation board is based on 150V 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 150V 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.
The EVAL_4kVA_230VAC_5LINV evaluation board supports a nominal 400VDC input voltage with operating range from 380V to 420V. The nominal output voltage is a 230VRMS, 60Hz pure sine wave. The maximum output continuous power of 4.0kVA. The inverter start-up time to reach the nominal output voltage during full-load condition is less than 500ms. An overload of 50 percent can be safely sustained for 10 seconds.
