The new energy converter and booster integrated machine is an optimized integration of medium-voltage high-power energy storage converter, switchgear, and step-up transformer. It features higher single-unit power, simple application, flexible installation site selection, and convenient operation and maintenance. The system can directly connect to the grid at 10/35kV high voltage, reducing the complex high-voltage system design work, shortening the system design cycle, and lowering the system design cost. The equipment includes oil-immersed transformers, PCS high and low voltage switchgear, etc., with voltage levels ranging from 6kV to 35kV and a capacity range of 0.5MW to 6.6MW.
