Huawei launches efficient rectifier at 98 percent conversion efficiency

SHENZHEN, CHINA: Huawei has recently released its latest rectifier featuring 98 percent conversion efficiency globally, the highest conversion efficiency ever released commercially for telecom equipment power supply systems.

The rectifier is a key component of telecom equipment power supply systems and rectifies alternating current (AC) into direct current (DC). Incorporating a number of patented technologies including MPII high efficient topology, MEPK intelligent algorithm and MSHT heat dissipation technology, the Huawei rectifier can now achieve a peak conversion efficiency of 98 percent even at 50 percent load ratio, the prevalent DC load, an upgrade from the previous 96 percent conversion efficiency.

At 98 percent conversion efficiency, Huawei's rectifier can further reduce conversion power loss by 50 percent compared to a mainstream rectifier in industry with 94 percent conversion efficiency.

The rectifier's higher conversion efficiency reduces heat dissipation, leading to improved power density as well as a 40 percent power failure rate reduction and a lowered noise level. In addition, with one rack unit in height and 42.7W/inch3 power density, the rectifier saves more than 30 percent cabinet space and footprint.

"Every 1 percent efficiency improvement of power supply system results in a huge amount of energy saving and profit increase, especially considering the fact that the combined annual income of the global telecom operators is over $2,000 billion. For a core networking room with a DC load of 500kW, a 2 percent efficiency improvement in power supply system would save at least 100,000kWh energy consumption, equivalent to the energy consumption of nine average US households for a year," said Dr. Fang Liangzhou, VP of Huawei Network Energy Product Line.

"Huawei's latest 98 percent conversion efficiency rectifier has redefined high efficiency conversion for power systems. We are proud to help our customers with energy conservation and help them move towards a more sustainable and ecologically sound business."
