1. Introduction
2. Hardware Description
This manual is valid for development kit version 1.0. It provides
guidelines to quickly setup the hardware for fast and easy evaluation
of the wireless charging system and the featured key components. For
further details and updates about the used parts, please consult
the relevant product datasheets and general information at
www.we-online.com/wirelesspower/200WKit, also for downloading
the latest version of this document and additional useful information
such as application notes, Gerber files, schematics, bill of materials,
firmware etc.
2.1 Block diagram
The development kit consists of the following components:
Transmitter board Demonstration of charging pad function using
MCU, discrete full bridge and TX coil
Receiver board Demonstration of wireless power receiver
inside a mobile device using synchronous
rectification and RX coil
Power supply Wide input range mains power supply with
different adapters for international use
A block diagram of the development kit is depicted in figure 2. The
transmitter design corresponds to a proprietary wireless power transfer
design using an XMC1302-T038X0064 to control the wireless power
transfer. The necessary 24 VDC input voltage is provided with the included
mains adapters.
The transmitter board contains the EMI-filter, reverse voltage protection,
full bridge, resonant tank and the control circuit. The power transfer is
fully digitally controlled by an XMC1302 series microcontroller. The
control signals for the full bridge are generated by the MCU and can be
controlled in automatic mode or manual mode. In manual mode the
switching frequency can be changed with the encoder. This can be used
to change the output voltage or for optimizing the efficiency.

2.3 Design advice
The switching frequency has to be higher than the resonant
frequency of the resonant tank, otherwise the output voltage can
reach a very high level.
The voltage in the resonant tank can be high. For this purpose
the voltage rating of the resonant tank capacitors have to be
considered.
Please keep in mind that when changing the output voltage the
efficiency will drop. As a consequence the temperature on some
parts will rise.

3. Development kit setup
and operating hints
3.1 Warnings
This development kit must only be operated by trained
professionals.
This development kit should be operated in a well ventilated
environment and, if used inside a case, the case should not
be covered.
This development kit should be placed on a stable, flat,
non-conductive surface in use and should not be contacted
by conductive items.
All peripherals used with the development kit should comply with
relevant standards for the country of use and be marked accordingly
to ensure that safety and performance requirements are met.
5
All cables or connectors used must offer adequate insulation and
operation in order that the requirements of the relevant performance
and safety are met.
The connection of incompatible devices to the development kit can
cause serious damage to the unit.
Do not short any outputs to each other, to the supply or to GND
Do no operate the development kit outside its specified ratings
Take care to monitor the PCB and IC temperatures in particular
when operating with high power loads and do not exceed the
absolute maximum ratings of all components
WARNING
The AC voltage in the resonant tank may reach voltage up
to 250 Vpp under certain conditions. Therefore, it is
covered by acryl glass to ensure human safety.
Nevertheless take care not to touch the PCB by bare hand
and use the required level of isolation when probing test
points on the PCB.
3.2 Instructions for safe use
Do not expose the development kit to water, moisture or place on a
conductive surface whilst in operation
Take care whilst handling to avoid mechanical or electrical damage
to the printed circuit board and components
Avoid handling the printed circuit board while it is powered. Only
handle by the edges to minimize the risk of electrostatic discharge
damage
3.3 Power supply
Apply one of the included mains plugs (North America / Japan, Great
Britain, Central Europe) to the power supply connector and connect the
AC plug to mains. Connect the DC plug of the mains adapter to J4 of the
transmitter board. In case another power supply is used please make
sure to comply with the electrical characteristics as the provided mains
adapter (see table 2). Take care not to reverse polarize the applied
voltage.

6. Step by step installation guide
for 200 W development kit
Step 1: Install software tools
Install DAVE™
DAVE™ is a free and powerful Eclipse-based development platform for
XMC™ software development.
DAVE™ includes GCC compiler from GNU, DAVE™ code engine for
automatic code generation and GDB debugger from GNU. DAVE™ offers
pre-defined and tested SW components -DAVE™ APPs- and XMC™
Lib-Low Level Drivers (LLDs) – that accelerate the application software
creation.
To install DAVE™ follow these steps:
Download and execute the latest version of DAVE™ installation file
from www.Infineon.com/DAVE
Follow the installation guidelines that are included in the download
package
Step 2: Power up setup
Make sure a load is connected to J4 on the receiver board and is
adjusted to 1 A before switching on the power supply unit. Connect the
transmitter coil to J5 on the transmitter board and the receiver coil to J5
on the receiver board (see figure 6).
Additionally a display board can be connected to the RS232 interface
(J2) of the transmitter board and a sensor with I²C interface to J6 of the
receiver board.
Step 3: Automatic and manual operation mode
By placing the jumper on position A/M on J1 (see figure 7) the transmitter
is set to manual mode. In this mode the switching frequency can be
adjusted between 100 kHz to 205 kHz referring to a coil distance of 6
mm. This function can be used to optimize the system performance or to
test different wireless power coils. When the jumper is removed the
switching frequency is set automatically to adjust output voltage to
19 – 20 V. This jumper is removed by default.
