Wireless Power Transfer

New challenges, but also new opportunities

By Cem Som / Jörg Hantschel

1. Introduction

The way consumers use smartphones has changed significantly in recent years. This
applies not only to all mobile devices but also to all electric appliances in industrial
and medical technology with and without batteries. Ever longer usage times and
higher power demands of the end devices either increase the demand for compact
and high-capacity batteries or the need to charge the devices wirelessly throughout
the day, which would mean the device needs to be integrated with the right wireless
charging technology.
To be successful, wireless charging must be simple and convenient to handle for the
user and have a charge performance (charge time, efficiency, ...) that is comparable
to conventional wire technology.

2. Application examples

Once the technology which is driven by consumer products (5–20 W), is established,
many kinds of applications over a wide range of industries will follow. We believe it will
be possible to charge a variety of devices in the area of mobile communications
technology (smartphones, tablets, digital cameras, fitness trackers, smart watches,
baby phones/walkie-talkies etc.) using a single charging device. Nowadays this can’t
be done because of all the different connectors, so wireless transmission of energy is
a gain in convenience and mobility for our customers.

We’re already transmitting energy wirelessly to charge batteries e.g. in electrical
toothbrushes, beard trimmers, and electric razors. New applications, such as for
hairdryers or styling irons, would be possible and would avoid annoying cords and
therefore increase the safety significantly.

In our kitchens we could use different appliances (power class 200 W – 2.4 kW) via
wireless energy transmission. Applications such as rice cookers, water boilers,
breadmakers, mixers, egg boilers and frying pans can be operated directly without
having a chargeable battery as energy supply.

In medical technology, wireless energy transfer is used to supply energy to implants
and wireless endoscopes, for biomonitoring (heart frequency, EKG, temperature, blood
pressure, neural activity), blood composition (oxygen saturation, blood glucose, carbon
dioxide, pH values), stimulation (pacemakers, muscle stimulation, neurostimulators),
monitoring and adjustment (activity, bladder pressure, implanted insuline pumps) and

also for medical machines. Today the charge contacts are worn out by very aggressive
disinfection agents. If completely encapsulated, these devices can be sterilized and
using wireless energy transfer poses no major challenges for the casing technology,
because open contacts are no longer necessary.

In the industrial area, wireless energy supplies offer the solution for many problems
that occur today in devices with charging contacts in dirty, dusty or explosion-prone
environments. This increases not only the reliability and robustness of industrial
applications, but also their durability and thereby maintenance costs will be reduced.
Wireless energy transfer can be used in driverless transport systems, suspension
tracks, cranes, conveyor systems or for supplying sensors and actuators in pressure
containers and tanks.

If helmet lamps and gas detectors have integrated wireless charge technology, this
can prevent contact sparks in mining, refineries and chemical production.

Wireless energy transfer works very well under water and can be used with diving
robots, diving torches and underwater cameras. This is very important for the water
tightness at great depths because the casings can be completely enclosed.

3. The dominating standards

The success of these solutions of course depends on maintaining a standard for
transmitters and receivers. Only if there is assurance that the device can be charged
hassle-free at any charging station that meets the standard, regardless of the
manufacturer, the system will be successful. What kinds of standard approaches are
out there and what’s the technology behind them?

3.1 Wireless Power Consortium (WPC) – Qi Standard

„

„

Energy transmission with inductive coupling across short distances (mm range)
and also magnetic resonance with distances over 20–30 mm

„

„

Transmitter (Tx) and receiver (Rx) are inductively coupled coils.

„

„

The magnetic field is concentrated in the narrow region between transmitter and
receiver coil

„

„

Each transmitter can serve only one receiver

„

„

Different performance classes (5 W, 15 W, higher classes are planned up to
2.4 kW)

„

„

Frequency range 100–205 kHz

„

„

Coil forms: wound on ferrite or printed onto circuit board

„

„

Currently (01/2016) the most well-established solution on the market with over
940 licensed devices

Wireless Power Charging Coils

3.2  Air Fuel Alliance

1.   First charging principle is the magnetic resonance from the former standard A4WP

(Alliance for Wireless Power): A transmitter oscillatory circuit with a resonance
frequency provides the energy. Receivers correctly tuned to the resonance
frequency can absorb the energy

„

„

Greater distance in z direction (50 mm), and exact positioning of the receiver is
unnecessary

„

„

One transmitter can handle multiple receivers simultaneously

„

„

Performance class planned for smartphones and tablets currently up to 22 W

„

„

Frequency ranges: Energy 6.78 MHz (ISM band), data 2.4 GHz (LP Bluetooth)

„

„

First commercial products will be available in 2016

2.   Second charging principle is the inductive coupled solution from the former

standard PMA (Power Matters Alliance)

„

„

The inductive coupled solution uses a different protocol and transmission
frequency band (details for members only) than the Qi solution of WPC

„

„

No direct compatibility with Qi, dual standard receivers are available

3.3.  Proprietary system solutions

All standards have their advantages and disadvantages. However, around 30 % of
applications in industrial technology or medical technology are not reliant on being
compatible with other manufacturers or with other terminal devices. With this
fundamental elimination of compatibility, manufacturers from all industries, apart from
the consumer and automobile industries, are producing self-developed proprietary
system solutions. These proprietary system approaches do not always require
customer-specific passive components for wireless power transfer. Instead, WE-WPCC
standard transmitter and receiver coils can be used.

4. Basics

The Faraday Law of Induction describes the basic principle of energy transmission.

Fig. 1

Current flowing through the primary coil (transmitter coil) generates a magnetic flux
Φ

1

. This magnetic flux Φ

1

in the winding generates an induction voltage in the

secondary coil (receiver coil) based on the faraday´s law of induction (see fig. 1). As
transmitter coil and receiver coil are physically separate, only a portion of the
magnetic flux Φ

21

penetrates the receiver coil (and vice versa) which induces voltage

on the coupled coil and eventually supplies an appliance. This magnetic coupling
between two coils is described by the relation of the magnetic fluxes Φ

21

1

.

Coupling factor k is defined as follows:

k =

L

1

* L

2

M



M is the mutual inductance between both coils. L

1

and L

2

are the self-inductances of

both coils. The coupling factor is very dependent on the displacement of the coils in x
and z direction. The coupling can be improved by attaching ferromagnetic material to
the coil because this bundles the magnetic flux. The ferrite also protects parts of the
circuit near to the transmitter and receiver coils by lowering the induced interfering
voltage. The coupling factor with an ideal transformer is 1, but maximum coupling in
the range of 0.2 – 0.7 can be achieved with an inductively coupled system.

The quality factor Q of the coils has a direct impact on the coupling and efficiency of
the wireless energy transfer. Quality factor Q is defined as follows:

Q =

=

X

L

R

L

ω

0

* L

R

R: effective series resistance (ac resistance at operating frequency) of the coil
