Design of Inverter for Hand Tools Wireless Charger

Quentin CASSIER

Diplomová práce

Abstract:

This paper goes through the design of an inverter for hand held tools wireless charger. The resulting device should be compact and able to recharge devices at up to 600W with a high efficiency. Such system could be used to recharge cordless power tools but could also be applied to most other battery powered device like laptops or drones. Such charger can also be useful in case of harsh environment which prohibit the use of connectors like in explosive or medical area. The first part of this paper focus on component choices to fulfil requirements such as space constraints, heat dissipation and electromagnetic compatibility. The second part is about printed circuit board layout and the issues encountered during the design. The third part cover the possibility of control and the programming of the inverter. And finally, the last part describes the realisation and testing of the inverter.
