The principle of operation of the inverter generator is based on the use of an inverter system. First of all, it includes the control of pulse width modulation, which is capable of producing electricity of very good quality. All this was made possible thanks to the adjusted output voltage with a stable frequency.
The inverter generator begins with the operation of a rectifier that generates direct current from an alternating current. Next, the pulsation is cleaned, which is stabilized by special filters. Then, alternating current begins to appear in the bridge circuit with the help of transistors, as well as special keys. In some power plants, thyristors are additionally used. The output current parameters are monitored in all areas. As a result, the frequency will always be stable. Feedback loop parameters are controlled by an inverter generator system.
Internal organization
An inverter-type multipolar generator consists of two parts. The first block includes a rotor with a three-phase network, which operates as a permanent magnet in the system and additionally has a stator. The second part of the multipolar generator is called the inverter unit. It consists of a rectifier, a filter, as well as a conversion circuit, which produces an alternating voltage as a result. The process is monitored by a microcomputer.
Generator work
When the generator starts, the rotor immediately begins to quickly gain momentum. The rotation occurs directly near the stator. As a result, a three-phase alternating current is generated. Then it goes to the inverter unit, where it passes through the rectification circuit, which equalizes the voltage and stabilizes its output indicators. The conversion circuit makes the voltage sinusoidal. As a result, alternating current exits the inverter unit. The microcomputer is responsible for the current frequency signal and provides voltage parameters.
Inverter Generator: Reviews and Benefits
Inverter gasoline power plants have several advantages. First of all, it is saving resources. The ignition system, which is installed in the inverter generators, can significantly save fuel. This is due to a sophisticated control system that is fully automated. With increasing load on the generator, the engine speed will increase. When the loads are small, the power plant reduces speed and fuel consumption is reduced. As a result, the economy mode is able to protect the system from overloads on the inverter generator. Feedback on this feature is only positive.
The second advantage of inverter generators is the type of connection between the system and the motor. Direct connection to the generator motor eliminates the additional installation of a flywheel. Ultimately, this affects the mass and size of the power plant. Without a flywheel, the generator weighs significantly less, which facilitates its transportation, and the small size of the device allows you to install it in almost any place.
All modern inverter-based gasoline power plants are air-cooled. Thanks to him, the motor can withstand heavy loads for a long time. The casing for noise reduction allows you to install an inverter generator in close proximity to people. Customer reviews indicate the superiority of such an apparatus over diesel power plants, which operate much louder. Some models of inverter generators have a dual noise reduction system. Such a casing is able to reduce sound to a minimum, even in powerful power plants.
It should also be noted environmental friendliness of inverter generators. The fuel combustion system is set up in a power plant in such a way that emissions to the atmosphere from its operation are negligible. As a result, the environment does not suffer, and people, without harming their health, can safely use inverter generators for the home.
