Question

What are the types of inverters?

Answer 1

Inverters are like a small compulsory electronic device, on which many of our other main electronic equipment depends. They are extensively used, not only because of their universal function of converting DC power to AC power but also because of their high efficiency, reduced power costs, and versatile applications. To classify the different types of inverters based on various factors affecting the system.

Complete step by step answer:
An inverter refers to a power electronic device that converts power in DC form to AC form at the required frequency and voltage output. Hence we can classify various kinds of inverters based on the output characteristic, source, load, PWM Technique, and Output levels.
According to the Output Characteristic we can classify as
Square Wave Inverter
Sine Wave Inverter
Modified Sine Wave Inverter
According to the Source of Inverter, we can classify as
Current Source Inverter
Voltage Source Inverter
According to the Type of Load, we can classify it as
Single Phase Inverter
a) Half Bridge Inverter b) Full Bridge Inverter
Three Phase Inverter
a) 180-degree mode b) 120-degree mode
According to different PWM Technique, we can classify as
Simple Pulse Width Modulation (SPWM)
Multiple Pulse Width Modulation (MPWM)
Sinusoidal Pulse Width Modulation (SPWM)
Modified sinusoidal Pulse Width Modulation (MSPWM)
According to Number of Output Level, we can classify as
1. Regular Two-Level Inverter
2. Multilevel Inverter

Note:
Alternating Current (AC) power supply is used for all the residential, commercial, and industrial needs. But the biggest problem with AC is that it cannot be kept for future use. So AC is converted into DC and then DC is kept in batteries and ultracapacitors. And now whenever AC is needed, DC is again converted into AC to run the AC-based appliances. So the device which alters DC into AC is called Inverter. The inverter is useful for converting DC to variable AC. This variation will be in the magnitude of voltage, number of phases, frequency, or phase difference.
