(1) Using PWM pulse width modulation technology, four-quadrant operation, accurate output phase, and effective suppression of high-order harmonics;
(2) Adopt DSP2812 processor, fast speed, high precision, good stability and strong anti-interference ability;
(3) Voltage distortion rate <5%, in line with IEC61000-3-2 and GB/T14549 requirements for grid harmonics;
(4) Improve the braking effect and adapt to the engineering needs of rapid braking and frequent braking;
(5) It can be used in parallel for higher power occasions;
(6) Equipped with a touch screen, which can display AC current, voltage, power and fault information;
(7) It has the functions of over-under-voltage, short-circuit, over-heating, and overload;
(8) Feedback: the use of self-diagnostic technology to ensure the accuracy of the output voltage, to prevent current loopback, so that the inverter is not affected in any way;
(9) Energy-saving: the regenerated energy is fed back to the power grid with an efficiency of 97%, which increases the economic benefits of operation and saves energy and protects the environment;
(10) Substitution: the use of braking unit + resistance = energy feedback brake, which is a complete replacement;
(11) Safety: adopt advanced power electronic technology and high-performance IGBT as switching devices;
(12) Practicability: The system has good power saving effect, low heat generation, high safety, and small maintenance workload;
