Power management carries great importance for in all systems. Power electronics basically examines energy control and transformation of energy forms into each other. Power electronics is made up of two parts; first is the energy management and the second is transformation of energy.

In aviation sector, hardest stage of power electronics is the cooling of heated integrations of power electronics elements. Heat emerges due to loss during the energy transformation. It is important to maintain fault-free function under hard conditions by carrying out temperature analysis and simulation tests in order to prevent this heat to damage other systems and keep working temperature range of modules within required parameters.
