Bonfiglioli Agile rate of occurrence converters
The Agile Bonfiglioli line rate of occurrence converters set new standards in inverter technology for a wide range of users. Agile inverters are particularly suitable for the food, textile, woodworking, packaging and ceramic industries, where they can be used in various automation processes of medium complexity.
Frequency converters are devices designed to convert alternating current (voltage) of one frequency into alternating current (voltage) of another frequency.
The output frequency in modern converters can vary over a wide range and be either higher or lower than the frequency of the supply network.
The power part is usually made on thyristors or transistors that operate in electronic key mode. The control part is performed on digital microprocessors and provides control of power electronic keys, as well as the solution of a large number of auxiliary tasks (control, diagnostics, protection).
Thus, the output voltage of the Converter is formed from the" cut-out " sections of the sinusoids of the input voltage. For rice.5. an example of generating the output voltage for one of the load phases is shown. At the input, the three-phase sinusoidal voltage ia, IV, and IC acts as a winner for thyristor devices. The output voltage of the ivy has a non-sinusoidal "sawtooth" shape, which can be approximated by a sinusoid (thickened line). The figure shows that the frequency of the output voltage can not be equal to or higher than the frequency of the supply network. It is in the range from 0 to 30 Hz. As a result, the engine speed control range is small (no more than 1: 10). This restriction does not allow the use of such converters in modern frequency-controlled drives with a wide range of technological parameters regulation.
