Development of Wireless Charging Receiver (English)
Abstract [sv]

Detta examensarbete handlar om trådlös batteriladdning. Arbetet har utförts genom Jörgensen Industrielektronik AB, ett företag som specialiserat sig på kundanpassade elektroniklösningar. Företaget utvecklade en ny produkt, där det skulle finnas som tillval att den kunde laddas trådlöst. En mottagare för trådlös laddning av produktens batterier utvecklades. Mottagaren utvecklades utifrån Qi-standarden som beskrivs i denna rapport. Mottagarens elektriska egenskaper bestämdes (t.ex. effektivitet och laddström). EMCtester av mottagaren utfördes för att undersöka hur mycket störningar mottagaren genererade.

Arbetet resulterade i en mottagare som kunde ladda produktens batterier med en befintlig Qi-laddstation. Effektiviteten hamnade på en nivå som är vanlig för trådlös laddning, jämfört med ledningsbunden laddning så var effektiviteten lägre. Resultatet av EMCtesterna visade att mottagaren genererade elektromagnetiska störningar, men emissionsnivåerna var inom gränserna för de EMC-standarder mätningarna har jämförts med.

Abstract [en]

The subject of this thesis is wireless battery charging. The thesis has been made in collaboration with Jörgensen Industrielektronik Ltd, specialized in costumer adapted electronics. The company developed a new product, where wireless charging was an optional feature. In this thesis a wireless charging receiver was developed. The receiver was intended for charging the batteries in the product. The receiver was developed according to the Qi standard. The Qi standard is described in this report. EMC tests were performed on the receiver in order to examine the levels of emissions radiated.

The work resulted in a receiver that was able to charge the product's batteries with an existing Qi charging station. The efficiency was normal for wireless charging, compared to wired charging the efficiency was lower. The EMC tests showed that the receiver radiates electromagnetic energy. The radiated emissions were within the limits of the EMC standards that the measurements have been tested against.
