THERMOGRAPHIC ANALYSIS OF A BRIDGE POWER CONVERTER

Anna V. Andonova – Nikolay L. Hinov

   Any loss of power in converters is dissipated as heat in the components of the circuit. The article presents a new approach to measuring heat dissipation in a bridge power converter with hard switches using infrared thermography. Parallel measurements by thermocouples have been carried out. The experimental results are compared and used from the both cases. The proposed approach can be used for various circuit implementations of the converters in a similar manner.
