超磁致伸缩换能器驱动器设计
Design of driver in super-magnetostiction transducer
【摘要】 稀土超磁致伸缩换能器是一种新型的可控震源。本论文针对稀土超磁致伸缩换能器并结合浅层地震勘探的特点,研制了稀土超磁致伸缩换能器驱动器。该驱动器由计算机PCI总线FPGA信号发射卡、IGBT驱动器、IGBT逆变器及电源组成。由该驱动器和稀土超磁致伸缩换能器组成震源系统,将其应用于浅层地震勘探模型试验中,取得了良好的效果。
【Abstract】 Rare-earth super-magnetostriction transducer is a new type of vibroseis. To counter the rare-earth super-magnetostriction transducer and in combination with the characters of shallow seismic exploration, we developed the driver of rare-earth super-magnetostriction transducer. The driver consists of FPGA signal transmission card of com puter PCI trunk, IGBT driver, IGBT (dc-to-ac) converter and power. The source system consisted of the driver and rare-earth super-magnetostriction transducer was applied to the tests of shallow seismic prospecting model, which achieved good results.
【Key words】 rare-earth super-magnetostriction transducer; driver; shallow seismic exploration; IGBT (dc-to-ac) converter; PCI signal transmission card;
