Modern electronic systems cannot function without three-phase inverters, which transform DC power into three-phase AC power with adjustable amplitude, frequency, and phase difference. They are essential in several applications, including as power distribution networks, renewable energy systems, and industrial motor drives.
The output stage of the three-phase inverter primarily comprised a dual closed-loop control system utilizing the SVPWM modulation algorithm, an NPC three-level inverter circuit, an LC filter circuit, and a three-phase load module. Based on the SVPWM algorithm, the maximum amplitude of the three-phase voltage output was Udc2 /3 ½.
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.
In a three-phase inverter , the pole voltage , which represents the voltage applied to the load , is equivalent to the pole voltage in a half-phase inverter used in single-phase applications . However in three-phase inverters , this voltage is distributed across three phases to create a balanced three-phase AC output .
