● By adopting a dual DSP+FPGA collaborative control method, high-speed computation and parallel processing of logical data are achieved, ensuring the real-time, efficient, and reliable performance of the system.

● Adopting high-performance space voltage vector control technology or enhanced VVVF control technology to achieve high output torque and fast dynamic response of the system. The use of phase-shifting transformers to form a multi pulse rectification method greatly improves the current waveform on the grid side, making the relative harmonic content of the input current less than 1.5%, directly meeting the harmonic suppression requirements of IEEE519-1992

● Standards. In addition, the input power factor can reach up to 0.96, eliminating the need for additional input harmonic filters and power factor compensation devices.

● The multi-level carrier phase shifting technology controlled by SPWM is adopted to superimpose the fundamental phase of the output and cancel out the harmonics, thereby achieving a voltage output waveform of approximately perfect sine wave after multiple power units are connected in series. The relative harmonic content of the output voltage is less than 1.8%, so there is no need to add an additional output filter.

● Equipped with instantaneous power outage restart function: When the power grid is interrupted and then restored, the machine can automatically return to the operating state before  the power outage. Strong adaptability to grid fluctuations, when the grid voltage drops to 65% of the rated value, The device is still functioning properly.

● System can switch frequency converter worry free: In case of frequency converter failure or maintenance, the motor can be switched worry free to the power frequency circuit to ensure that production is not affected. Bypass cabinet (optional)

● Automatic switching; At the same time, there is a UPS backup power supply (30 minutes) to ensure the safety and reliability of the control system. Flexible operation: The frequency converter adjusts the acceleration time or limits the motor operating frequency based on the current load current of the motor, thereby limiting the  current and achieving the function of overcurrent during the acceleration process. Frequency reduction of frequency converter Adjust the frequency reduction time according to the magnitude of the bus voltage during the process, in order to achieve the function of not overvoltage during the frequency  reduction process.

● Current limiting technology: When the frequency converter is turned on and running, if the current exceeds the limit value, the increase in current is limited by frequency  reduction until the current is below the limit value, and the frequency converter returns to normal operating frequency

●Overvoltage stall technology: During the frequency reduction operation of the frequency converter, when the motor generates electricity and the  bus voltage rises, the frequency converter automatically prolongs the frequency reduction time to prevent shutdown problems caused by bus  overvoltage.

●Fiber optic communication technology: Fiber optic communication is used between the power unit and controller to  further enhance the real-time communication of the system. The high and low voltage parts are completely electrically  isolated, greatly increasing the system's anti-interference ability.

● Human machine interaction interface: Large screen color LCD touch screen human-machine interface, simple operation,  rich display content, support on-site parameter setting, logic control editing, permission setting, operation data information  query, etc. Additionally, it supports remote monitoring and networked control. 

● Encoder (optional); Used for mixing machine application scenarios, monitoring motor speed, closed-loop speed control. 

●Cooling system: Adopting internationally renowned brand fans in the industry, with large air volume, sufficient margin,  long service life, and high stability, it ensures the cooling needs of high-voltage frequency converters and improves product  stability
