Research on Acoustic Generator Driver Circuit Used for Downhole Communications

摘要：

This paper introduced a acoustic generator driver circuit application for downhole communications. High-speed SOC icrocontroller is as a controlling core, the SPWM table off-line made with special arithmetic processing stored in ROM. Through PCA function module reading the SPWM data to produce the SPWM pulse sequence, greatly simplified the hardware design and program design, also optimized for driver circuit, driver mode, and so on. The whole circuit structure is simple and its working is stable and reliable. The results showed that this driver circuit can fully meet for downhole acoustic telemetry system.
