Three-phase power factor correction technology in electromagnetic transmitter

摘要：

　　Electromagnetic transmitter is an important part of controlled source electromagnetic sounding system.To ensure that the receiver obtains a signal with high SNR (signal to noise ratio) at sufficiently large depth with high accuracy, a large power transmitter is required.In China and abroad, the high-power transmitters are generally bulky, heavy, and has low power transmission.However, the use of three-phase power factor correction technology can solve the above problems.A simple and practical power control strategy was presented in this study.This can achieve the power factor of one.
