We all know about inverter - it is a device which converts DC into AC. And we previously learned about Different types of inverters and built a single phase 12v to 220v inverter. A 3 Phase Inverter converts the DC voltage into 3 Phase AC supply.
However in three-phase inverters , this voltage is distributed across three phases to create a balanced three-phase AC output . There are two primary conduction modes in both single-phase and three-phase inverters i.e.. 120-degree conduction mode and the 180-degree conduction mode.
Although the output waveform is not a pure sine wave, it did resemble the three-phase voltage waveform. This is a simple ideal circuit and approximated waveform for understanding 3 phase inverter working. You can design a working model based on this theory using thyristors, switching, control, and protection circuitry.
If we draw the voltage waveforms for each phase then we will have a graph as shown in the figure. In the graph, we can see three voltage waveforms are out of phase with each other by 120º. In this article, we will discuss 3 Phase Inverter Circuit which is used as DC to 3 phase AC converter.
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.
