摘要：
To detect deep mineral resources and achieve high-voltage output with low-voltage devices, a novel transmitter based on modular multilevel converter(MMC) was proposed, which adopted modular structure and was formed by cascaded half-bridge sub-modules(SM) to share high voltage stress. By establishing the equivalent circuit, the principle of adjusting the rising and falling edges of the transmitting current was analyzed. The transmitting current in a cycle was divided into eight segments using a segmented control strategy, and the segmented currents were precisely controlled. The simulation model was built in MATLAB/SIMULINK, and a prototype of the four-level MMC transmitting system was built to further verify the feasibility of the system. The results show that compared with the H-bridge transmitter, the proposed transmitter has faster current rising and falling edges, which improves detection efficiency. © 2022 Central South University of Technology.
