2AOR81909004Wireless Charger providing a USB Type-C interface

Installation Guide Installation Guide 1. Purpose The purpose of this document is to provide information on how to integrate the Wireless Power Transmitter (Model: 81909005) and Receiver (Model: 81909004) with FCC ID: 2AOR81909004 into a final application. Incorrect integration or use may infringe compliance rules meaning recertification may be required. 2. Module Description The Wireless Power modules (Tx= power transmitter, Rx = power receiver) are designed to provide a high efficiency power transmission of up to 13.5W to an USB Type-C device. This power transmission is using a pair of tightly coupled power coils. An additional pair of inductive coupled coils is used to transfer control information from the power receiver back to the transmitter to provide a safe operation at the optimum working frequency. The power transmission module input voltage is 24V DC. To maximize the system efficiency, the power transmission between Wireless Transmitter and Receiver is realized using resonant circuits. These resonant circuits additionally provide the ability to vary the transmitted power by changing the switching frequency. By increasing the switching frequency, the available power on the receiver side de-creases. For an accurate output voltage regulation, a control loop is necessary. The output conditions like output current, voltage and power are measured on the receiver side and sent to the power transmitter. If corrections are necessary, the transmitter will change the switching frequency to the desired value. An appropriate control loop needs a fast signal transmission with little delay. This transmission is accomplished using a second pair of coupled coils. Like the power transmission coils, the signal coils form a near field coupling system thus the intended use of radio waves isn’t necessary. Installation Guide The following picture shows a block diagram of the complete system including Transmitter and Receiver. Installation Guide 3. Application Examples The system is designed to be used as a Wireless Charger for USB Type-C powered devices in medical environments (e.g. tablets). The Wireless Power Transmitter must be mounted on and powered by a base station. The Wireless Power Receiver can be connected with the USB Type-C device either using an USB type C compliant cable. The USB type-C device together with the Wireless Power Receiver can be used in mobile applications, the base station including the Wireless Power Transmitter is stationary and not intended for mobile usage. In order to start the charging process, the Power Receiver must be placed close to the Power Transmitter. Charging will only take place during non-mobile stationary usage. The power transmitter is stationary and the power receiver will be installed inside a non-stationary device. The power receiver and the device which will be charged are to be mounted in the same enclosure, so it’s not possible for hum The picture shows the use cases “Not Charging” and “Charging”. The Power Transmitter is depicted yellow, the Power Receiver red. The following pictures shows an example application where the Wireless Power Transmitter is wall mounted on a computer-tomography scan unit and the Receiver is connected to a tablet which is used for supervision. In this situation the tablet isn’t charging. Installation Guide The following pictures shows part of the front of a medical stationary device. The Transmitter is mounted behind the front and not accessible on back and side: The following pictures shows the backside of the front of the stationary medical device where the Transmitter is mounted: Installation Guide The following pictures shows the enclosure for both Wireless Receiver and tablet with Receiver mounted and tablet not mounted. The following pictures shows the enclosure for both Wireless Receiver and tablet with Receiver and tablet mounted. The tablet is connected with the Receiver using an USB-cable (see picture above and section “Integration into products”. USB Type C compliant Flex- Cable Receiver Enclosure Enclosure Enclosure USB Type C Connector connected with tablet Tablet USB Type-C Connector Tablet Installation Guide The following pictures shows the enclosure with tablet and Wireless Receiver put on top of the stationary medical device. This is the typical setup for the charging tablet: Installation Guide 4. Integration into Products Transmitter The input connector of the Wireless Power Transmitter is a TE Connectivity 1-178293-3. The Wireless Power Transmitter shall be mounted using the mounting holes provided by the manufacturer. M4 screws and hex nuts are recommended. Receiver The Wireless Power Receiver supplies a USB Type-C compliant power to the host application. The following picture shows the USB type C output connector: The Wireless Power Receiver shall be mounted using the mounting holes provided by the manufacturer. M3 screws are suitable, e.g. Screwerk STP 3803000803 or comparable. The cable to supply the load shall be USB Type-C compliant. Installation Guide The following picture shows the system mounted in a final example application without the tablet. Installation Guide 5. Antenna design The following picture shows the antenna design. The antenna is carried out on a 1mm PCB using traces of 200u width, the distance between the windings is 200u. As shown in various EMC tests, no intended radiation is used to transmit data. All information is transmitted using the principle of near field coupled coils utilizing a carrier frequency of 2MHz. The coil area used is 440 mm². Installation Guide 6. Regulatory Information FCC This device complies with Part 15 of FCC Rules, Operation is Subject to following two conditions: 1) This device may not cause harmful interference, and 2) This device must accept any interference received including Caution: Any changes or modifications to the equipment not expressly approved by the party responsible for compliance could void user’s authority to operate the equipment.
