Telecom equipment vendor Huawei has released its latest rectifier featuring 98 percent conversion efficiency. The new breakthrough offers significant benefits to mobile operators such as China Mobile, Bharti Airtel, etc.
Huawei says this is the highest conversion efficiency ever released commercially for telecom equipment power supply systems.
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 reduce conversion power loss by 50 percent compared to a mainstream rectifier in industry with 94 percent conversion efficiency.
Huawei says it incorporates patented technologies including MPII high efficient topology, MEPK intelligent algorithm and MSHT heat dissipation technology.
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.
“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 Fang Liangzhou, vice president of Huawei Network Energy Product Line.
