一种多频阵列电测井信号发生及驱动系统
摘要：
一种多频阵列电测井信号发生及驱动系统，主要由信号发生单元、信号放大单元、信号隔离单元、高频驱动单元组成。信号发生单元的输出端与信号放大单元的输入端相连接，信号放大输出端与信号隔离单元的输入端相连接，信号隔离的输出端与高频驱动的输入端相连接。其中信号发生单元可输出62.5kHz～10MHz的任意波形信号。信号放大单元可实现62.5kHz～10MHz信号的放大，信号隔离单元可隔离瞬变大电流信号，避免误触发，通过高频驱动单元，最终实现62.5kHz～10MHz、0～1kW高频大功率MOSFET器件的驱动。
摘要（英）：

A signal generating and driving system for multi-frequency array electrical logging is mainly composed of a signal generating unit, a signal amplifying unit, a signal isolating unit and a high-frequency driving unit. The output end of the signal generating unit is connected with the input end of the signal amplifying unit. The output end of the signal amplifying unit is connected with the input end of the signal isolating unit. The output end of the signal isolating unit is connected with the input end of the high-frequency driving unit. Any wave signals of 62.5 kHz-10 MHz can be output by the signal generating unit and the signals of 62.5 kHz-10 MHz can be amplified through the signal amplifying unit. Transient large current signals can be isolated by the signal isolating unit, so that false triggering is avoided and a 62.5 kHz-10 MHz and 0-1 kW high-frequency and large-power MOSFET device is finally driven through the high-frequency driving unit.
