Control of Three-Level T-Type Power Supply for Magnetostrictive Transducer

As a device for underwater sounding, magnetostrictive transducer is the core equipment for marine development and naval power. The current quality of the magnetostrictive transducer has a significant impact on its performance. In this paper, the control scheme of three-level T-type power supply for magnetostrictive transducer is proposed to make the transducer output linear frequency modulation signal. Based on the control scheme, the current quality of the magnetostrictive transducer can be improved even under the unbalanced voltage in shipboard power system. Finally, the experiments are proposed for verifying the effectiveness of the control scheme for the power supply.
