High-efficiency conversion aids solar challenge
High-efficiency low-power DC/DC convertors from C and D Technologies will play a key role in a solar-powered vehicle being built to compete in this year's World Solar Challenge in Australia
High-efficiency low-power DC/DC convertors from C and D Technologies are playing a key role in a state-of-the-art solar-powered vehicle being built to compete in this year's World Solar Challenge in Australia. The Umicore Solar Team is the first Belgian team to enter the World Solar Challenge, which requires a vehicle to travel more than 3000km from Darwin to Adelaide powered by nothing but the sun.
The race will take around five days with the vehicles averaging speeds in the region of 100km/h.
Known as the Umicar, the Umicore team's vehicle uses 2800 solar cells to power an electric motor and all of the onboard electronics and telemetry systems, which are based around a CAN network.
To help the team develop the vehicle, C and D Technologies has provided a number of its LME1205S isolated DC/DC convertors.
These single-output, 250mW devices are used to isolate the CAN nodes and to convert the 12V bus network down to 5V.
Key reasons for choosing the devices were their high efficiency operation and high levels of integration.
Discussing the selection of the DC/DC devices, Jeroen van Aken, one of the 14 engineering students that make up the Umicore team, comments: 'High efficiency, small size and low weight are key design criteria for a solar-powered vehicle'.
'The LME1205S devices help us to address these criteria while minimising the need for additional external components'.
Rob Hill, the Vice President of Global Marketing Communications for C and D's Power Electronics Division adds: 'As a global manufacturer C and D Technologies is committed to doing all that it can to support environmental responsibility'.
'While the Solar Challenge is undoubtedly fun it also has a serious role to play in furthering the cause of research into the viability of solar power'.
'We are pleased that we can help support this cause by providing the Umicore team with key components they need to complete their design'.
