Loss and thermal analysis and design of a time-domain electromagnetic detection transmitter
摘要
Abstract
Electromagnetic detection technologies is widely used in mineral exploration, archaeological research, environmental safety testing and other fields.As one of the electromagnetic detection technologies, the time domain electromagnetic detection technology has characteristics of great depth, high efficiency and low cost, so it has a broad application prospect.Because of the great power of the time-domain electromagnetic detection system, the loss and thermal efficiency is large.How to reduce the loss and thermal efficiency has become the focus of the study.By using PLECS with multiple advantages, such as simple operation, good stability, well-equipped devices and fast simulation speed, the theory calculated the average loss of inverter circuits of full-bridge converters.Our study designed a thermal simulation model of time-domain electromagnetic detection transmitter.On this basis, this research analyzed the average loss of uncontrollable rectifier circuits and inverter circuits of full-bridge converters, and calculated the maximum thermal resistance value of radiators on both sides of a high-frequency transformer.The simulation shows that the proposed method is simple and accurate.It effectively prevents the excessive design of radiators, improves the design efficiency of the system and ensures the stability of the system.Besides, it also provides a thermal simulation basis for further establishing a prototyping model and shortens the experimental process of the model establishment.关键词
