| 摘 要： | 用超磁致伸缩材料做成的换能器具有输出力大、响应速度快的特点,这就要求其驱动电源瞬间能输出较大的电流以形成强磁场.由于该换能器是处于间歇工作状态,利用电容的储能原理制成的驱动电源能满足要求,其关键的难点是储能电容的容量要与换能器线圈的参数相匹配,才能得到良好的效果.可用Matlab软件,通过计算机辅助分析的方法确定储能电容的参数值.储能电容的充放电转换开关可用继电器或场效应管实现.实验表明,该电源可用小型的充电电池供电,并具有连续工作时间长,工作可靠,瞬间输出功率大,体积小、重量轻的特点,特别适合野外使用.

| Abstract: | Energy transducer mode of giant magnetostrictive materials has great output and quick response speed.This requires the driven power supply to export for an instant bigger electric current to form strong magnetic field.As the transducer is at intermittent work state,so we use the principle of capacitance stored energy to make driven power supply.The key point is that the capacity of the stored energy capacitance should match the parameters of transducer coil.By software Matlab,this article designed the param... |
