Technical FAQs 4

What is a square wave inverter?

The square wave inverter is the simplest and least expensive, but it is seldom used today. One drawback to square wave and modified sine wave inverters is that they tend to produce electrical noise (interference) that can be troublesome for electronic equipment.

What is an inverter bridge?

The inverter bridge (H-bridge) is a method of producing a square wave from a DC voltage. The operation of a basic H-bridge is enhanced to produce the misnamed modified sine wave, which is shown in Figure 5. (Perhaps modified square wave would be a better name.)

What are the different types of power inverters?

These transistors made it possible to develop new power inverters that are much more efficient (some are over 97% efficient) than older analog switching inverters. There are three basic types of inverters in terms of the type of output: sine wave, square wave, and modified sine wave as shown in Figure 2.

What is the output waveform of a two-level inverter?

The output waveform of a two-level inverter resembles a square wave or a modified sine wave, depending on the modulation technique used. Two-level inverters are relatively simple in design and widely used in various applications such as motor drives, renewable energy systems, and UPS (Uninterruptible Power Supply) systems.
