Abstract In the artificial source electromagnetic exploration, it is important to keep the transmitting current steady. On the basis of analyzing the normal current-regulation technology, the authors put forward a high-precision digital current-regulation technology. An example is also given to illustrate the software and hardware designing method based on the technology.
