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.
In a 3 phase, the power can be transmitted across the network with the help of three different currents which are out of phase with each other, whereas in single-phase inverter, the power can transmit through a single phase. For instance, if you have a three-phase connection in your home, then the inverter can be connected to one of the phases.
The DC power source of the three-phase current-type inverter, i.e., the DC current source, is achieved through a variable voltage source using current feedback control. However, employing only current feedback cannot reduce the power ripple in the inverter input voltage caused by switch actions, resulting in current fluctuations.
This way, an inverter regulates voltage. Three-phase modulation modulates all of the three phases of a three-phase inverter simultaneously (to generate a sinusoidal PWM signal) whereas two-phase modulation modulates two of the three phases at any one time while holding the other phase at High or Low level.
The three-phase square wave inverter as described above can be used to generate balanced three-phase ac voltages of desired (fundamental) frequency. However harmonic voltages of 5th, 7th and other non-triplen odd multiples of fundamental frequency distort the output voltage.
A three phase bridge inverter is a device which converts DC power input into three phase AC output. Like single phase inverter, it draws DC supply from a battery or more commonly from a rectifier. A basic three phase inverter is a six step bridge inverter. It uses a minimum of 6 thyristors.
