Abstract

This application provides a DC power supply multiple output protection circuit unit, a protection circuit and an underwater robot. This application belongs to the field of underwater robots. The technical solution provided by the application aims to solve the problem that the underwater robot loses its working ability when a short-circuit failure of some components occurs. Wherein the protection circuit unit for the multi-channel output of the DC power supply of the underwater robot includes: an input terminal; an output terminal; a load voltage detection circuit for detecting the voltage of the output terminal; a switch circuit for controlling the connection between the input terminal and the The conduction / disconnection between the output ends; the pre-charging circuit, when the switch circuit is turned off, charges the output end from the input end with current limitation. The technical solution provided by this application can be used for the power supply management of each component of the underwater robot.

Description

technical field [0001] This application belongs to remote-controlled underwater robots, in particular to a protection circuit unit for multiple outputs of DC power supplies for underwater robots, a protection circuit for multiple outputs of DC power supplies for underwater robots, and a remote-controlled underwater robot . Background technique [0002] At present, the electronic systems of remote-controlled underwater robots are becoming more and more complex, and their reliability requirements are also increasing. The electronic system of the remote-controlled underwater robot generally includes a DC stabilized voltage power supply and several loads. When a load has a short-circuit fault, it will trigger the over-current or short-circuit protection function of the DC regulated power supply. The power supply will generally stop outputting as a result, causing the entire device to shut down. Contents of the invention [0003] Based on this, the application provides a pro...
