Robot power supply system

Abstract

A robot power supply system disclosed by the present invention comprises a power supply circuit, an EMI filter, a rectifying and filtering circuit, a soft start circuit, a protection circuit, a drive circuit, a sampling circuit, a power conversion circuit, a pulse width modulation circuit and a comparing and amplifying circuit. The two ends of the power supply circuit are connected with the EMI filter, an output end rectifying and filtering circuit and the sampling circuit separately, the EMI filter is also connected with the rectifying and filtering circuit and the protection circuit separately, and the rectifying and filtering circuit is also connected with the soft start circuit. The robot power supply system of the present invention satisfies the loads of different powers by changing the number of the power supply modules, each module bears the smaller electric stress, and the small-power power supply modules and a large-scale control integrated circuit are used as the basic parts, so that the research and development pressure of the large-power components and devices is relieved substantially, the thermal design is simplified, and a power supply keeps the higher efficiency and reliability. The soft start circuit can effectively prevent the situation that a switching power supply absorbs a larger current at the electrification moment, so that the efficiency reduces.

Description

technical field [0001] The invention relates to a robot, in particular to a robot power supply system. Background technique [0002] With the development of social productivity and the advancement of multimedia processing technology, people have higher and higher requirements for robot functions. [0003] The use of robots is inseparable from the power supply system. Robots generally use high-power power supply, which is a branch of the power supply field. High-power power supply is usually realized in two ways, one is directly designed according to power requirements. The other is to use multiple low-power parallel output designs. The maintenance of the former system is complex, such as heat dissipation design, noise management, and efficiency management, which must be managed in a centralized and unified manner to achieve the overall design goal. The latter adopts the existing mature circuit design, and then performs parallel connection. There is no problem of heat diss...

Problems solved by technology

[0004] However, the cost of parallel design is high, the system is not synchronized, and it is easy to cause mutual influence. If it is not handled properly, some will have high efficiency and some will have low efficiency. They will work in an asynchronous state, which will eventually affect the power quality.
