How much power can a three-phase grid convert?
When interfacing three-phase grid, the design can convert steady state maximum power of 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 a three-phase AC/DC converter?
Three-phase currents, voltages and their corresponding phase shifts are shown when having the AC/DC converter working respectively as a PFC, inductive load, inverter and capacitive load. The currents and voltages have a constant amplitude, thus implying constant apparent power. Figure 34. Operating region of a three-phase converter.
What is the difference between a single phase and a three phase converter?
Overview: Single Phase vs. Three Phase For a given power requirement, a three-phase converter requires less current, is a smaller size, and produces less power ripple than a single-phase converter. For example, an 11-kW single-phase PFC requires 48 A, while an 11-kW three-phase PFC requires only 16 A per phase.
How do you calculate the efficiency of a three-phase PWM inverter?
The efficiency η of a three-phase PWM inverter can be calculated using where P in is the input power of the inverter, P out is the output power of the inverter, P Inductor is the AC filter inductor loss, and P Device is the power device loss. 14
