责备受害人为吸血鬼设备是没有办法ergy efficiency
UK energy supplier British Gas hit the headline last week with a report that focused on ‘vampire devices’ that consume power while plugged-in but on standby.
This was a way to help consumers reduce costs with record high electricity process across Europe.
Unfortunately the report turned out to use old data from 2015 in the US, and even then shot itself in the foot. The survey British Gas commissioned around the data found that only 16% of respondents had never heard of vampire devices, and most weren’t overly bothered.
The reason was clear in the data. A mobile phone charger plugged in costs just £1.26 (€1.50) a year in energy costs. Internet routers, which consume £18.89 (€25.00) a year increasingly need to stay powered-up to provide vital online services.
这位受害者指责还对已经创新十年来创新的电力工程师造成了损害，以提高电力转换设备的效率，并满足欧盟越来越紧密的能源规格，以消除这些吸血鬼装置的效果。

Power designers from around the world are meeting in Nuremberg, Germany, this week for the PCIM exhibition and conference and are highlighting the dramatic advances.
New designs in both silicon and gallium nitride are driving up efficiencies. Moving from 95% to 97, 98 or even 99% efficiency, especially at low load, cuts the power losses by up to 80%, making a dramatic contribution to energy efficiency.
The higher frequencies of GaN are allowing smaller charger designs. This allows the chargers to fit into power sockets where eliminating that low load, vampire drain is vital. Companies from ST Microelectronics and Infineon in Europe to Navitas, GaN Systems, EPC and Transphorm in the US and Rohm in Japan are using GaN to drive up the efficiencies of all kinds of consumer equipment.
但是硅的创新也在继续前进。Silanna和新控制器一起使用硅和GAN设备，就像意大利的Eggtronic一样。两者都有内存的设计。Vicor还使用硅控制器的模块，使用谐振转换拓扑达到99％的效率。使用模块可以将所有电容和感应元件包含在谐振频率中，以达到该峰值效率。
The incremental improvement in energy efficiency is a vital part of tackling the issues of energy security and global heating. Power engineers are at the forefront of this challenge, and victim-blaming designers and consumers for vampire devices is short-sighted and unthinking.
