Design of Power Transformer in MTEM Transmitter Power

Multi-channel high-power electrical prospecting instrument (MTEM) transmitter is developed on the basis of the bipolar switching power's principle.Thedesign ofthe transformer'smain components is critical to the performance of MTEM transmitter system.The dual-input dual-output 60KW of power transformers was designed afteranalysistheworksprinciple ofbipolar full-bridge power transformer.TheFinite Element Analysis softwareMaxwell builta 3D model of the transformerand analyzed its internal distribution of the electromagnetic field. While the transformerhasbeen designed out to put intousein the MTEM transmitter system, and applied in the relevant fieldexperiment. The simulation and experiment indicated that this transformer is designed reasonablywith small ripple, low loss, low temperature, high efficiency, stability and reliability.
