<p>The frequency converter is a power control device that uses frequency conversion technology and microelectronic technology to control the AC motor by changing the frequency of the working power of the motor. It is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit, micro-processing unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by turning on and off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the frequency converter has many protection functions , Such as overcurrent, overvoltage, overload protection, etc. With the continuous improvement of industrial automation, the inverter has also been widely used.</p><p><br></p><p>The characteristics of the inverter:</p><p><br></p><p> ①Multiple PWM control is adopted, and the output voltage waveform is close to a sine wave.</p><p><br></p><p> ②The multiplexing of the rectifier circuit has many pulses, high power factor, and small input harmonics.</p><p><br></p><p> ③ Modular design, compact structure, easy maintenance, and enhanced product interchangeability.</p><p><br></p><p> ④Direct high voltage output, no need to output transformer.</p><p><br></p><p> ⑤ Extremely low dv/dt output, without any form of filter.</p><p><br></p><p> ⑥Some adopt optical fiber communication technology to improve the anti-interference ability and reliability of the product.</p><p><br></p><p> ⑦ The automatic bypass circuit of the power unit can realize the function of non-stop failure.</p><p><br></p><p>V&T Technologies is a professionl <a href="https://www.vectorque.com" rel="noopener noreferrer" target="_blank">vfd manufacturer</a>.
