Research on Thermoelectric Energy Conversion System for Controller in Magnetic Bearing

Abstract:

In order to prevent damage caused by instantaneous power failure to high-speed equipment, the thermoelectric energy conversion system for controller of magnetic bearing is studied. The heat source is used by the power loss of supply modules and the cold source is used by heat conduction aluminum block. The semiconductor thermoelectric generator produces direct-current working voltage between heat source and cold source. The overall design method of the energy conversion system is presented. The theory and design of circuits to thermoelectric energy generator, voltage regulator and charging for lithium polymer battery are analyzed. The experiment results show that this thermoelectric energy generator system is feasible and effective. The circuit can be adapted to change in output power due to temperature difference at both ends of the thermoelectric module. It achieves energy storage of the recovery from thermoelectric generator.
