All You Need to Know About a Single Phase Inverter

Continuously upgrading technology is making our life easier, like smart watches for 24/7 surveillance of our physical health, invertors for unprecedented outages and more. With the ever-increasing consumption of electricity and power outages, inverters are in high demand. Moreover, with the introduction of different types of inverters in the market, like three-phase and single phase inverter connections, the ease of doing work at home and in offices is now easier. 

With the Covid-19 pandemic and the rise in work-from-home, single phase inverters sales have been at a record high. In addition, inverters help provide power to the equipment when the utility power is off or a big outage occurs due to rain or other factors.   

Inverters are the energy backup systems for homes as well as offices. They convert direct current (DC) to alternating current (AC). Because direct current cannot travel long distances, it is transformed into Alternating Current (AC). Moreover, if the power source is solar or battery, the DC is converted to 110/220 volt alternating AC. 

Another benefit of AC is that, unlike DC, which can only flow in one direction, it may occasionally shift direction and experience both rise and fall. The voltage also periodically reverses when the current changes direction in an AC circuit. In this article, we will talk all about single phase PWM inverters. 

So, without further ado, let’s read on!

Single Phase Inverter: An Overview  

Inverters’ main electric power source is the DC source, i.e., the battery. As per the user’s requirements, the DC converges into AC using the DC-AC inverter. An inverter’s job is to convert a dc input voltage to an ac output voltage with the apt magnitude and frequency. 

Therefore, single phase inverter connection should have sinusoidal output voltage waveforms. However, the waveforms of actual inverters are not sinusoidal and include certain harmonics. In the below section, we will discuss the type of inverters we can choose as per the requirements.  

Types of Inverters

All the inverters are classified as per the output waveform and load. Here we will be discussing two main types of inverters:  

1. Single Phase Inverter

As you can understand by the name, a single phase inverter connection has a single-phase power load and alternating switches to counterbalance them. A single phase inverter connection is classified into a full-bridge inverter and a half-bridge inverter. The full-bridge inverter has four feedback diodes and four switches.   

The current load is balanced by automatically turning off two switches when two are turned on. In addition, they establish whether the voltage is positive or negative during the half-cycle. On the other hand, a half-bridge inverter has two switches coupled to two diodes that control the voltage output cycle. 

2. Three-Phase Inverter  

The three-phase inverter is used in industries with much more power than the single phase inverter. These inverters use three switches, six diodes, and a three-phase output to produce alternating currents. Then, depending on the switches’ conduction times, the current is split into a different degree mode, like 180 or 120 degrees.  

Are Single Phase Inverters Better than Three Phase Inverters?

The load capacity of single phase PWM inverters and three-phase inverters is different. Single phase inverter connection can handle up to 7500 Watts or at least 10 horsepower. So, you must know how much load your home appliances generate or require; if the required load exceeds 7.5Kw, then you should use the three-phase inverter. 

So, choose the inverter as per the load your home power can handle and also install the inverter as per your load requirement. 

Tips to Choose the Best Single Phase Inverter for Home

If you are not sure what is the right inverter to choose for the home, then the points below are here to help you:  

1. Calculate your power requirements as a first step. That is to say, decide how many devices you have, considering the fans, lamps, Wi-Fi routers, and charging ports. After that, find out how much energy is used, and choose the best inverter for your house. 

2. Calculate your load and research the various inverters available in the market per your need.  

3. The size of the battery is crucial to meeting all of your needs. The right backup will be provided with no problems and with the proper battery size for longer periods. You must determine the battery size for how long you need your home’s power backup. 

Single phase PWM inverters can be used in various applications. So, are you looking for the best single phase inverter connection for your home or office to ease your working processes? If yes, look at our diverse range of single phase inverters options on the website as per your requirements.
