Find The Best Inverter

Inverter

An inverter converts the DC voltage to an AC voltage. In most cases, the input DC voltage is usually lower while the output AC is equal to the grid supply voltage of either 120 volts, or 240 Volts depending on the country.


The inverter may be built as standalone equipment for applications such as solar power, or to work as a backup power supply from batteries which are charged separately.


Inverters, essential components in the realm of electrical and electronic engineering, perform a vital role in converting one form of electrical energy to another. The primary function of an inverter is to convert direct current (DC) to alternating current (AC), thereby enabling the use of domestic appliances that operate on AC when only a DC power source is available.

Benefits Of Inverter

Helps protect the engine
The inverter can change the speed of the motor easily, so the starting current of the motors will not be able to exceed 1.5 times of the traditional starting current. Inverters often have an internal electronic system to help protect against overcurrent, high voltage and low voltage conditions, helping to create a safe system during operation.
Helps reduce mechanical wear
During the start-up process, the inverter will help the motor’s speed to be started from a steady low, not start suddenly, this will help the motor carry a large load to avoid mechanical damage. and bearing, which increases the life of the motor.
Help save electricity
Compared with the traditional starting system, the inverter will help save electricity up to 20-30%. Since the inverter can be easily changed in speed, saving energy for the loads will not need to run at its full capacity.
Help improve technology
The reactive power from the motor is very low, almost ignored, so it will reduce the current significantly during operation, reduce the line shortage, and reduce the installation cost of the capacitor bank.

Types Of Inverter

Standalone inverter

Standalone types of inverter are connected directly to the load and are not interrupted by other power sources. Stand-alone inverters are types of inverter that power the load on their own without being affected by the grid or other power sources.


These inverters cannot be connected to the utility grid because they do not have synchronization capabilities, where synchronization is the process of matching the phase and nominal frequency (50/60hz) of two AC sources. And they can work with off grid batteries system.

Single phase inverter

Single-phase inverters convert DC input into single-phase output. The output voltage/current of a single-phase inverter has only one phase, and its nominal frequency is a nominal voltage of 50Hz or 60Hz. Nominal voltage is defined as the voltage level at which an electrical system operates.

Single-phase losses are greater, and single-phase efficiency is lower than three-phase inverters. Therefore, three-phase inverters are the first choice for high loads.

Voltage source inverter (VSI)

When the input of the inverter is a constant DC voltage source, the inverter is called a voltage source inverter. A voltage source inverter has a rigid DC voltage source at its input with zero impedance. In practice, the impedance of a DC voltage source is negligible.

Parallel inverter

The parallel inverter consists of two thyristors, a capacitor, center-tapped transformer and an inductor. Thyristors are used to provide a path for the current to flow, while inductors are used to make the current source constant.

The switching on and off of these thyristors is controlled by commutation capacitors connected between them. The reason why it is called a parallel inverter is that in the working state, the capacitor is connected in parallel with the load through the transformer.

Line commutated inverter

In these types of inverter, the line voltage of the AC circuit is available through the device. When the current in the SCR experiences a zero characteristic, the device is turned off. This commutation process is called line commutation, and the inverter that works based on this principle is called a line commutated inverter.

How do Inverters Work?

Conversion Process
The primary function of an inverter is to transform the DC electricity supplied by sources like batteries, solar panels, or fuel cells into the AC electricity used by most household appliances and devices. This process involves changing the direction of current flow and altering the voltage to generate a sinusoidal AC waveform.

DC-to-AC Conversion
The inverter’s main circuitry consists of electronic components, including transistors or insulated gate bipolar transistors (IGBTs), capacitors, and control circuitry. These components work together to rapidly switch the direction of current flow, creating an oscillating voltage that produces an AC waveform.

Pulse Width Modulation (PWM)
Modern inverters often use a technique called Pulse Width Modulation (PWM) to generate the AC waveform. PWM involves switching the transistors on and off in a rapid sequence, varying the width of the pulses. By adjusting the pulse width, the inverter can control the magnitude of the output voltage.

Sine Wave Generation
Inverters aim to produce an AC waveform that closely resembles a sinusoidal waveform, which is the standard form of AC power from the grid. This is essential for compatibility with appliances and devices that require a stable and consistent AC supply. In high-quality inverters, the PWM technique is used to approximate a pure sine wave output.

Control Circuitry
The inverter’s control circuitry plays a crucial role in regulating the output voltage and frequency. It ensures that the AC waveform generated by the inverter matches the specifications required for safe and effective operation of connected devices.

Output Filtering
After the waveform is generated, output filtering components such as capacitors and inductors help smooth out any fluctuations and harmonics in the AC output. This filtering ensures that the AC power provided by the inverter is of high quality and free from unwanted noise or distortions.

How to Maintain Inverters

Cleaning and Inspection

  • The first step in maintaining an inverter is to inspect and clean it regularly. Checking for dust, dirt, and debris is critical as they can accumulate inside the inverter and cause overheating or short circuits. It is essential to ensure that the inverter is free from any foreign materials that may cause damage or reduce its lifespan.
  • To clean the inverter, turn off the power supply and disconnect any cables. Use a soft-bristled brush or a dry cloth to gently remove any dust or debris from the exterior of the inverter. Do not use water or any liquids to clean the inverter, as it may damage the internal components.
  • After cleaning the exterior, inspect the inverter for any signs of wear and tear, such as cracks or corrosion. Check the wiring connections for any loose or damaged wires. If there are any issues, it is best to contact a professional electrician to repair or replace the damaged components.


Battery Maintenance

  • The battery is a crucial component of an inverter system, and it requires regular maintenance to ensure optimal performance. Checking the battery water level is one of the critical tasks in maintaining an inverter. The water level in the battery should be checked regularly and maintained at the recommended level. If the water level is too low, it can cause damage to the battery, reducing its lifespan.
  • If the battery is damaged, it is essential to replace it immediately. A damaged battery can cause system failures or pose safety hazards. It is also crucial to charge and discharge the battery regularly to ensure that it remains in good condition. A battery that is not used regularly can lose its capacity to hold a charge, reducing the overall performance of the system.


Ventilation
Proper ventilation is critical for the optimal performance of an inverter. The inverter generates heat during operation, and without proper ventilation, it can overheat and cause system failures. It is essential to ensure that the inverter has adequate ventilation to dissipate heat.
