What is PD IEC/PAS 63095‑1 – Qi wireless power transfer systems about?
PD IEC/PAS 63095‑1 is an international standard that discusses the interface of the Qi wireless power transfer system power class 0 specification.
PD IEC/PAS 63095‑1 defines the interface between a Power Transmitter and a Power Receiver, i.e., Power Class 0 Base Stations and Mobile Devices. Power Class 0 is the WPC designation for flat-surface devices, such as chargers, mobile phones, tablets, cameras, and battery packs, in the Baseline Power Profile (≤ 5 W) and Extended Power Profile (≤ 15 W).
Who is PD IEC/PAS 63095‑1 – Qi wireless power transfer systems for?
PD IEC/PAS 63095‑1 on Qi wireless power transfer systems applies to:
- Manufacturer of wireless power devices
- Electrical engineers
Why should you use PD IEC/PAS 63095‑1 – Qi wireless power transfer systems?
Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link.
The Wireless Power Consortium (WPC) is a worldwide organization that aims to develop and promote global standards for wireless power transfer in various application areas. A first application area, designated Power Class 0, is wireless charging of low and medium power devices, such as mobile phones and tablet computers. The Wireless Power Consortium maintains the Qi logo for this application area.
PD IEC/PAS 63095‑1 provides the main features of the Qi wireless power transfer systems:
- A method of contactless power transfer from a Base Station to a Mobile Device that is based on nearfield magnetic induction between coils.
- Very low standby power is achievable (implementation-dependent)
- Considerable design flexibility for integration of the system into a Mobile Device.
- A simple communications protocol enabling the Mobile Device to take full control of the power transfer
- A Baseline Power Profile supporting the transfer of up to about 5 W and an Extended Power Profile supporting the transfer of up to about 15 W of power using an appropriate Secondary Coil (having a typical outer dimension of around 40 mm).
PD IEC/PAS 63095‑1 provides you with guidance on electromagnetic interface and thermal interface. It also provides a system efficiency where the efficiency of a wireless power transfer system depends on the combination of the specific Power Transmitter and the specific Power Receiver that are used, as well as their alignment.
