What parts of the inverter composition
The main converter are: rectifier module, inverter module, capacitor, driver board, motherboard, shell composed of these parts!
Frequency control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. However, due to the environment, the use of life and man-made operation and other factors, affecting the life of the inverter greatly reduced, while the use of a variety of failures have occurred. Here we are on the composition of the inverter and common problems and countermeasures and we discuss. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
Simply put, the inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit
