Tips: Variable frequency drive development trend

Low electromagnetic noise and mute
In addition to using the high frequency carrier sine wave SPWM modulation to achieve low noise, the VFD input side plus AC reactor or active power factor correction circuit APFC, and the inverter circuit also using SOFT-PWM control technology to improve the input current waveform, reduce the harmonic wave of the grid. The VFD meets the EMC international standard in anti-interference and inhibits the higher harmonic, and to achieve clean energy conversion.
Customization
The new VFD in order to better play the unique function of frequency control technology, and as far as possible to meet the needs of field control, derived from a number of customization models such as fan water pump air-conditioning dedicated model, heavy machinery dedicated model, AC elevator dedicated model, textile machinery dedicated model and so on.
Systematic
In addition to the development of digital, intelligent and multi-functional, the VFD is also developing to the integrated and systematic direction. The purpose is to provide the best system functions for users.
Network
The VFD can provide a variety of compatible communication interface, and can support a variety of different communication protocols. The built-in RS485 interface is able to input operation command and set the function code data from the computer.
