Technical FAQs 3

What is ref_11kw_pfc_sic_QD?

With the size of 243 mm x 100 mm x 40 mm (excluding cooling plate) and the power density of 11.3 kW/L, i.e., 185 W/in3, REF_11KW_PFC_SIC_QD demonstrates a viable approach for achieving high power density and efficiency, in the combined three-/single-phase AC-DC power converter unit compared to state-of-the-art solutions.

Can a power converter withstand high-voltage insulation?

Depending on system-level requirements, many power converter designs must withstand high-voltage insulation levels, typically in the range of several kilovolts between active circuitry and protective earth.

What is the peak efficiency of a PFC inverter?

11 kW in both power-flow directions, i.e., either PFC mode or inverter mode, with peak efficiency of 99.15 % (PFC) and 99.122 % (inverter) with 230 VRMS grid voltage.
