Leiditech recommends frequency converter protection devices and solutions
The frequency converter mainly consists of rectifier (AC to DC), filter, inverter (DC to AC), braking unit, driving unit, detection unit, microprocessor unit, etc. Frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
The frequency converter adjusts the voltage and frequency of the output power supply by breaking the internal IGBT, providing the required power voltage according to the actual needs of the motor, thereby achieving energy conservation and speed regulation. In addition, the frequency converter also has many protection functions, such as overcurrent, overvoltage, overload protection, and so on. With the continuous improvement of industrial automation, frequency converters have also been widely used. With the development and comprehensive utilization of high-speed frequency conversion technology, the frequency converter industry has achieved unprecedented development and application in industries such as industry, medicine, communication, transportation, power, electronics, and environmental protection. Almost all industries in the national economy are inseparable from frequency converters. Variable frequency speed regulation is considered the most ideal speed regulation scheme due to its high speed regulation accuracy, low startup energy consumption, small footprint, advanced technology, rich functions, simple operation, strong universality, and easy formation of closed-loop control, representing the development direction of electrical transmission.
