Photovoltaic converters: Reducing size, weight and cost through higher switching frequencies and lower losses

https://techxplore.com/news/2023-11-photovoltaic-size-weight-higher-frequencies.html

"50 kW PV inverter switching frequencies increased 2.5–3X for the DC input and by 10–12.5X for inverter output... enable high switching frequencies usually only achievable with Wide Band Gap... additional circuits consist of specialized combinations of auxiliary power semiconductors, resonance capacitors and inductors, reduce voltage and/or current stresses... loss reduction: Si-based IGBT of boost converter up to -70 % and for SiC-based MOSFET of inverter up to -92%... battery, drive of fuel cell converters"
