The principle of the inverter generator is builton the use of an inverter system. First of all, it includes control of pulse width modulation, which is capable of producing very good quality electric power. All this became possible due to the adjusted output voltage with a stable frequency.
The operation of the inverter generator begins withThe work of a rectifier, which produces a constant current from a variable. Further, 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. Output current parameters are monitored at all sites. As a result, the frequency will always be stable. The parameters of the feedback loops are controlled by the inverter generator system.
Internal organization
Multipolar Inverter Generatorconsists of two parts. The first unit includes a rotor with a three-phase network that operates as a permanent magnet in the system and additionally has a stator. The second part of the multipolar generator is called the inverter block. It consists of a rectifier, a filter, and also a converting circuit, which produces an alternating voltage as a result. The process is monitored by a microcomputer.
Generator operation
When the generator starts, the rotor starts immediatelyquickly gain momentum. Rotation occurs directly near the stator. As a result, three-phase alternating current is produced. Then it goes to the inverter block, where it passes through the rectification circuit, which equalizes the voltage and stabilizes its output. The transforming circuit makes the voltage sinusoidal. As a result, an alternating current is output from the inverter unit. The microcomputer is responsible for the current frequency signal and outputs the voltage parameters.
Inverter Generator: reviews and benefits
Inverter gasoline power plants have a number ofadvantages. First of all, this is saving resources. The ignition system, which is installed in inverter generators, is able to save much fuel. This is due to a thoughtful control system, which is fully automated. With increasing load on the generator, the engine speed will increase. When the loads are small, the power plant reduces the speed and fuel consumption is reduced. As a result, the economical mode is able to save the system from overloads to an inverter generator. Feedback about this function is only positive.
The second advantage of inverter generatorsis the type of connection of the system to the engine. Direct connection to the generator motor eliminates the additional installation of the flywheel. Ultimately, this affects the mass and size of the power plant. Without a flywheel, the generator weighs considerably less, which facilitates its transportation, and the small dimensions of the apparatus allow it to be installed in virtually any place.
All modern gasoline power stations inInverter-based air-cooled engine. Thanks to it, the motor can withstand heavy loads for a long time.
