About Delta Inverter Application

The frequency converter is the company's pioneering work, and it is also a product with a large sales volume of automation equipment. In the highly competitive market, Delta's inverters have maintained a strong growth momentum, and have gained a lot in the high-end products market and the economic products market. In the application field, after the OEM market achieved an unshakable market position, in 2008, Delta inverters turned their attention to a wider field - elevators, lifting, air conditioning, metallurgy, electric power, petrochemicals and energy-saving emission reduction projects. They are all long-sleeved and good-spirited places. In the process of participating in these projects, the ability of Delta's inverter team to provide system solutions has also been enhanced. At the same time, Delta has continuously launched high-end products, expanding its application in the high-end field, and winning the competition in the increasingly hot-selling inverter market. The Variable-frequency Drive (VFD) is a power control device that uses an inverter technology and a microelectronics technology to control an AC motor by changing the frequency of the motor's operating power supply. The frequency converter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, and detection unit micro processing unit. The inverter adjusts the voltage and frequency of the output power supply by the breaking of the internal IGBT, and supplies 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 and so on. With the continuous improvement of industrial automation, inverters have also been widely used.
