The fixed-voltage on the side of the AC side. After that Inverters convert the input power into the output power. The convert will happen with the highest power efficiency. There are different kinds of inverters. But not all are suitable for use in terms of the main supply.

The efficiency of an inverter depends on the fraction of its rated power. At which power it is operating. The performance of an Inverter depends on its points of work. The main application of an inverter is wave shaping, voltage regulation of output voltage, etc.

Considering on compressors inverters offers the best system to avoid inefficient on/off cycles. This system reduces seasonal efficiency. An inverter’s input voltage, output voltage, and frequency depend on the design of the specific device. Inverter basically does not produce any power. The power is provided by the DC source.

According to the Output Characteristic, there are three types of Inverter. These are

Sine Wave- Sine Wave considered as a true or pure sine wave

• Modified Sine Wave
• Square wave

According to the source, Inverter is two types. These are:

1. Current Source Inverter
2. Voltage Source Inverter

According to the Type of Load, there are two types of Inverter. These are:

• Single Phase Inverter
• Three Phase Inverter

 According to different PWM techniques, there are 4 types of Inverter. These are:

1. Simple Pulse Width Modulation (SPWM)
2. Multiple Pulse Width Modulation (MPWM)
3. Sinusoidal Pulse Width Modulation (SPWM)
4. Modified sinusoidal Pulse Width Modulation (MSPWM)

 According to the Number of Output Level, Inverter is two types. These are:

• Regular Two-Level Inverter
• Multi-Level Inverter

• 220V, 1-Phase
• 220V, 3-Phase
• 440V, 3-Phase
• Keypad
