Servo power supply

Abstract

The invention provides a servo power supply which is applied to an electromechanical servo system and belongs to the electromechanical field. The servo power supply source comprises a lithium battery pack (1) and a power supply management unit (2). The power supply management unit (2) is composed of a main control unit (2.1), a monomer voltage detection unit (2.2), a battery equalization management unit (2.3), a battery thermal management unit (2.4) and a peak compensation unit (2.5). The lithium battery pack (1) provides a power supply required by the electromechanical servo system. The power supply management unit (2) carries out peak current compensation and regeneration energy absorption, and carries out system management and equalization on the lithium battery pack (1). The servo power supply provided by the invention can work for a long time, can be reused, has the advantages of large capacity, high reliability, low cost and small volume, can absorb regeneration energy, can carry out large pulse discharge, and is especially suitable for an aerospace servo power supply system.

Description

technical field [0001] The invention relates to a power supply technology of an electromechanical servo system, which is used to complete the power supply of the electromechanical servo system on the fly, and belongs to the electromechanical field. Background technique [0002] Due to its simple structure, high reliability, short production cycle, simple test and convenient maintenance, the electromechanical servo system has broad application prospects in the aerospace field. The electromechanical servo system has gradually moved from the previous low power level to medium power and high power develop. With the development of aerospace model applications in the direction of low cost and reusability, new requirements are put forward for electromechanical servo systems, which require high servo operating voltage, high average load power, small installation space, strict weight requirements, and long-term power supply and Repeatable functions.

AI Technical Summary

Problems solved by technology

The power consumption of electromechanical servo systems has the characteristics of randomness, large pulse discharge, and the existence of regenerative electric energy. It is difficult for traditional servo power supplies to fully meet the requirements of all working conditions of electromechanical servo systems.

Servo power supply not only needs to meet the requirements of increasing power density and low cost, but also needs to meet the requirements of high voltage, high specific power, light and small size, and repeated use. However, there is no effective reusable, high-speed High-power, large-capacity electromechanical servo power supply
