Single Phase Inverter Question & Answers

February 22, 2023 By Wat Electrical

This article lists 75 Single Phase Inverter MCQs for engineering students. All the Single Phase Inverter Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Single Phase Inverter.

A device that converts DC to AC-type current at a specific frequency or voltage is called an inverter. As in AC power, a variable voltage and variable frequency are required. The power source, transformer, and transistors are the components of an inverter.

They are classified based on properties such as output characteristics (Square wave, sine wave, modified sine wave), and source type (current source, voltage source).

The load connected (Single phase, Three phases), and output characteristics. A single-phase inverter is further classified as half bridge and full bridge; whereas a three-phase is further classified as 180 degrees and 120 degrees.

Uninterruptible power supplies, solar power systems, and SMPS are a few of the applications of single-phase inverters. The benefits of inverters include effective cooling, compatibility for larger applications, and eco-friendly.

The disadvantages are high repair conditions and maintenance, quite expensive.
