Thermal Interface Material Challenges for DC/DC Power Control Modules
As the demand increases for electric vehicles (EVs) and hybrid electric vehicles (HEVs) worldwide, manufacturers must also cope with the increase in 12V or 24V accessories that traditionally have been powered by an alternator. In EVs and HEVs, this alternator is replaced with a DC/DC converter which can transfer the energy between the power source and on board accessories.
The amount of heat dissipated is dependent on the output load and converter efficiency. The control and evacuation of this heat is called thermal management. Prudent thermal management will result in long term reliable operation and allow maximum power utilization in a minimum amount of space.
