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.
At 3% phase current rms ripple, based on simulations, the full-bridge system requires a device average switching frequency of 61.4 kHz, whereas the three-phase inverter requires a 92.2 kHz device average switch-ing frequency (three-phase to full-bridge switching frequency ratio of 1.5).
Here, we present a motor drive design that highlights a significant advantage in using three single-phase inverters over a three-phase inverter. The system parameters of a 3.666 kW three-phase, high-speed motor drive operating at 2.046 kHz fundamental frequency, 3.01% rms phase current ripple, and /Vdc . are summarized in Table I.
5) Three-Phase Two-Level Inverter Three-phase converters are more commonly used in comparison to single-phase half-bridge or full-bridge converters. When examining the circuit diagram of a 3-phase bridge converter, it becomes evident that the converter is composed of six switching devices, with two devices allocated for each phase.
