Freescale的无线方案中有Qi v1.2吗?
引用:
Qi v1.2 will make it possible to charge devices from a
greater distance, meaning you don’t need to physically
leave your phone on a charging pad. The new chargers
reportedly work at up to 45mm away, compared to the
7mm allowed by earlier models. Qi v1.1 also functions
at up to 30mm away, and the WPC notes that v1.1 and
1.2 are compatible with one another.
WPC also revealed that the updated Qi standard could
be used to power kitchen appliances at up to 2,000
watts, potentially reducing the need for multiple outlets
in every room.
45毫米,2000瓦,厨房可以用--- 表示怀疑。
另:
坛里, 有做Qi v1.2产品的公司吗? 或做Qi v1.1经验,有能力做Qi v1.2的吗? 考虑定制合作

请看这个简单的ZVS电路,虽然功率不是很大,但是一样有比较强的高频磁场。不算效率功率300瓦,振荡频率130K正弦波。空载时距离30CM以内就明显感觉到头晕,手也有微热的感觉,这个与线圈的发热是不同的。感觉热不是手外到内的那种局部热。靠高频磁场绝对对人有辐射的。这玩意的感觉与我修电磁炉时的感觉一样的。我断定不是我的错觉。
