The invention discloses a deep sea motor high-power driver, and relates to the technical field of motor driving control. The deep sea motor high-power driver comprises an absolute value circuit, a driving circuit, a main control circuit, and a filter circuit, an APC circuit, a level conversion circuit, an upper bridge signal processing circuit and a lower bridge signal processing circuit which areconnected with the main control circuit. A voltage control signal is converted into a first preset voltage signal through the absolute value circuit, then is converted into a PWM signal through the APC circuit and is input into the main control circuit, meanwhile, the voltage control signal is converted into a logic signal through the level conversion circuit and input into the main control circuit, and a Hall signal output by a deep sea motor is input into the main control circuit through the filter circuit. The main control circuit outputs a control signal according to the PWM signal, the logic signal and the Hall signal, the control signal passes through the upper bridge signal processing circuit and the lower bridge signal processing circuit and then is input into the driving circuitto drive the deep sea motor to rotate in the designated direction, a complex control algorithm does not need to be developed by using the driver, driver efficiency is improved, and the development period is shortened.
Description
technical field [0001] The invention relates to the technical field of motor drive control, in particular to a high-power driver for deep-sea motors. Background technique [0002] Deep-sea equipment needs to use various actuators, such as hydraulic sources, seawater pumps or propellers, to navigate and operate in deep-sea environments. The deep-sea motor is the power source of many actuators, which is characterized by high power requirements, suitable for harsh working environments, and high reliability requirements. The efficient and reliable drive control of the deep-sea motor is the guarantee for the correct action of the actuator. At the same time, it is necessary to detect various status information of the deep-sea motor in order to understand the operating status of the deep-sea motor and ensure safety. Currently commonly used motor drive devices mainly include MOS tubes and IGBTs. MOS tubes are suitable for driving motors with low power, and the driving power of IGB...
