High pressure grade Federal Reserve energy converter
The topology of the high voltage cascaded energy storage system consists of grid-connected reactor, cascaded power unit, battery module, and corresponding control and protection equipment. Generation-side energy storage: load regulation, smoothing intermittent energy, increasing consumption of new energy, increasing reserve capacity of power grid, participating in peak regulation and frequency modulation. Transmission and distribution energy storage: improve power quality, reduce line loss, improve the reserve capacity of the grid, improve the utilization efficiency of transmission and distribution equipment, and delay the demand for capacity increase. User-side energy storage: smooth load curve, load transfer, peak clipping and valley filling. Emergency power supply system: it is in standby state when the power grid is normal, and it can be started when the power grid is faulty to guarantee the continuous power supply of the load. Fire power supply, emergency lighting, energy feedback, etc.

Special converter for rail transit
The special converter for rail transit adopts super capacitor as absorption and storage device.Its working principle is that when the train regenerative braking lead to an increase in dc voltage, equipment working in charging status, the energy stored in supercapacitors, when the train start lower dc voltage, equipment working in discharge from the super capacitor energy release to the dc traction network, better use of the braking energy, make the smaller dc voltage fluctuations.

The high-voltage four-quadrant (hoist) inverter
The high-voltage four-quadrant (hoist) inverter adopts advanced vector control technology. At the same time, vector control without rotary encoder can be used according to the site conditions. The main difference between vector control and traditional V/F control is that vector control can The reactive current is distinguished from the active current (torque current). During the lifting process, the active current can be automatically adjusted according to the change of the load to make the output torque reach a better working condition, and the output torque can be 2.5 times of the rated torque.
