Thermal Analysis of Voltage Converter for Autonomous Power Plant

A power supply that utilizes effective means for obtaining, accumulating and converting electric power is a topic of current interest in the modern energy. Semiconductor voltage converters are the essential parts of such electric systems and require to maintain the high reliability and reliability standards. Since the semiconducting equipment, as a rule, is characterized by a long duty operation it is extremely important to maintain the proper operating temperature of such electrical devices. This paper proposes the stabilizing voltage converter experimental model structure and design for an autonomous electric power plant with variable speed. In this paper a temperature analysis of power semiconductor device that contains a voltage rectifier, voltage converters and voltage inverter was carried out. The paper presents thermal analysis results – thermal profiles of the power devices and the heat sink are mapped and the implemented air cooling system capability is assessed. Obtained results could be used in design and development of electrical converting equipment for autonomous power supply systems.
