Abstract

The invention discloses a deep-sea long-distance mixed transmission high-power brushless direct-current motor driver. Through an input protection circuit, under the situation that a voltage is below a set value and a current is below a set value, direct currents are transmitted to an input filter circuit; the 300V direct currents are mainly transmitted to an inverter circuit after being filtered to form three-phase alternating currents in an inverting mode to drive a brushless direct-current motor to operate. A power supply converting circuit converts part of the filtered 300V direct currents to the voltage needed by a control module. A main control circuit can detect output signals of a Hall sensor in the brushless direct-current motor through a level switching and detecting circuit, so that signal waveform of the inverting circuit is switched and inverted. The deep-sea long-distance mixed transmission high-power brushless direct-current motor driver is small in size, high in efficiency and strong in stability, and interference on high-efficiency data signals in a data coupler from harmonic waves generated by the motor during operation can be lowered.

Description

technical field [0001] The invention belongs to the field of deep-sea energy transmission, and in particular relates to a high-power DC brushless motor driver for deep-sea long-distance hybrid transmission. Background technique [0002] As countries around the world pay more and more attention to the development of seabed mineral resources, in deep sea exploration, detection and other marine field projects, the power of specific equipment used is constantly increasing, and the way of information transmission is also constantly changing. The traditional energy and information transmission methods can no longer meet the needs. How to develop a high-power equipment drive system for the ocean according to the demand, reduce the interference of the equipment on the signal in the transmission circuit, and effectively improve the utilization rate of energy is the current ocean The key to energy transfer in development. In traditional deep-sea exploration, the energy and informatio...
