6 FAQs about Three-phase UPS to inverter

What is a 10kW three-phase UPS inverter?

A 10kW three-phase UPS inverter has been developed by Fraunhofer ISE with ROHM SiC and gate driver devices and can be seen in figure 4. The high switching frequency of 100 kHz leads to small passive filter components at the output and small input capacitors, which –apart from smaller size and weight – also leads to lower system costs.
