High-voltage shore power supply

Product Features

The device supports both 60Hz and 50Hz power supply modes; within the permissible capacity range of shore power inverters, variations in various loads (capacitive, inductive, or hybrid loads) do not adversely affect the output power quality, with voltage and frequency being continuously adjustable.
The system shall feature a hard-wired interface and a communication interface with the shore power inverter to facilitate communication, as well as enable control of the shore power inverter, including but not limited to the following functions: information exchange, parameter monitoring, and alarm generation.
The rated output is a three-phase sinusoidal power supply, and its power quality meets the user’s requirements.
The control system is equipped with synchronization functionality for grid connection to the ship’s power supply.
The shore power inverter employs an IGBT-based four-quadrant active rectifier, ensuring that the aerospace shore power inverter system does not introduce reactive power losses to the grid, while maintaining a power factor identical to that of the grid side.
The shore power inverter features protection functions against under-voltage, over-voltage, over-current, and over-temperature; the shore power inverter equipment can operate continuously at full load when the ambient temperature is below 50 °C.
