Matrix Converter Bi-directional Switch Power Loss and Cooling Condition Estimation for Integrated Drives

摘要

Matrix Converter Bi-directional Switch Power Loss and Cooling Condition Estimation for Integrated DrivesIn this paper power loss estimation of bi-directional switch of matrix converter is done by means of calculation and experiments. For safe operation of power devices an efficient cooling system of specific device must be designed. This work is part of a greater project of integrated matrix converter AC drives and the cooling problem here is viewed in context of this task. It is necessary to develop a compact power board and cooling system to extract excessive heat from power devices.
