Application scenarios:
1 . Data center power supply system
- Data centers have very high requirements on the stability and energy efficiency of power supply. Traditional AC Power supply requires multi -stage conversion (AC→DC→AC→DC) , with an efficiency loss of up to 15% - 20%.
- HVDC Can directly provide DC Power (e. g. 380v DC) , which reduces the conversion process and improves the overall energy efficiency (the efficiency can be more than 95%) .
utility + HVDC Direct supply: utility power is rectified to supply power directly to IT equipment, with batteries for seamless switching.
- HVDC+photovoltaic/Energy storage system: combining renewable energy and energy storage to build a low- carbon power supply system.
2 . communication base station power supply
- communication base stations (such as 5G base stations) are mostly DC loads ( - 48v DC) , and the traditional program needs to convert AC mains to DC , which is inefficient and complicated.
- HVDC Can directly output DC Power , simplifying the power supply link and reducing maintenance costs.
- china Mobile , Huawei and other companies are piloting 240v/336v HVDC power supply system to replace the traditional -48V Dc program , which is suitable for 5G base stations with high power consumption.
3 . Edge computing and microgrid
- Edge data centers or remote communication sites need independent power supply, and HVDC Can be combined with photovoltaic and energy storage to build off-grid or hybrid power supply systems.
