CHANG YIH(JANG YIH) frequency converter (VFD) is an advanced technology specially designed for the speed regulation requirements of AC motors, permanent magnet synchronous motors and reluctance motors. It adjusts the running speed of the motor by controlling the frequency of the power supply, so as to achieve the purpose of energy saving and efficiency improvement. There are many ways to classify inverters, among which, according to the working mode of the main circuit, they can be divided into voltage type inverters and current type inverters.
In terms of control methods, CHANG YIH(JANG YIH) frequency converter adopts a variety of advanced control technologies to ensure the operating efficiency and performance optimization of the motor. Including V/F=C sinusoidal pulse width modulation (SPWM) control mode, voltage space vector (SVPWM) control mode, vector control (VC) mode and direct torque control (DTC).
Closed-loop control (servo control) can be achieved through the combination of PG card and motor encoder CHANG YIH(JANG YIH) inverter can automatically select the most suitable output voltage according to actual needs, so that the motor is in a small current state during operation. This not only reduces the operating losses of the motor, but also further improves efficiency. Compared with the traditional speed regulation method, CHANG YIH(JANG YIH) inverter improves the efficiency on the basis of the original energy saving.
The benefits of using CHANG YIH(JANG YIH) inverter are not only reflected in energy saving and efficiency, but also can realize precise operation control and flexible speed regulation range. This is very important for various application scenarios that require variable speed operation, such as mechanical equipment in industrial production, air conditioning systems, water pumps and fans, etc.
As an advanced frequency conversion technology, CHANG YIH(JANG YIH) inverter improves the energy-saving efficiency and operating performance of the system by optimizing the operation mode of the motor. Its wide application will bring higher benefits and sustainable development opportunities to various industries.
