In essence , a 3-phase inverter is a crucial component for efficiently converting DC power into 3-phase AC power needed for various applications, especially in renewable energy systems like solar PV installations and industrial setups where three phase power is essential for running machinery and equipment.
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 .
A three-phase Voltage Source Inverter (VSI) with SPWM (Sinusoidal Pulse Width Modulation) is a type of inverter that converts DC voltage into three-phase AC voltage with sinusoidal waveforms. It works by varying the pulse width of a high-frequency carrier signal according to the instantaneous amplitude of a reference sinusoidal waveform.
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.
