Technical FAQs 4

What is the efficiency of a PFC rectifier & inverter converter?

When the converter is connected to single phase AC mains, the efficiency achieved is 98.95% in PFC rectifier mode and 98.95% in inverter mode. The efficiency results are obtained with the highest form factor/power density of 11.5kW/L.

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.

What is the efficiency and power loss of three-phase inverter mode?

Figure 51 and Figure 52 display the measured efficiency and power loss under three-phase inverter mode operation at different line voltages. The peak efficiencies of 99.263%, 99.122%, and 98.855% and the full-load efficiencies of 99.166%, 98.938%, and 98.632% are measured for the high-line, nominal, and low-line conditions, respectively.

What is the efficiency of a 180 VAC input?

For 180 VAC input, the full power is limited by the input 16 ARMS current. with full-load efficiency of 97.95% and peak efficiency of 98.66%. It is observed that efficiency is reduced by approximately 0.4% after half-load condition because of the power loss contibution from phase-leg C.
