Abstract

This is a non-contacting style rotable power supply converter. The output of the DC power supply is linked to the input of the control circuit, and the output of the control circuit is linked to the input of the premier winding of an electromagnetic coupler, the output of the secondary winding is linked to the input of a rectification circuit, and with a clearance between the premier and the secondary winding.

Description

technical field [0001] The invention relates to a non-contact rotating power converter which transmits electric energy to a rotating part under a rotating working condition, and belongs to the technical field of power conversion. Background technique [0002] In order to improve the accuracy and adequacy of the characteristic test of the rotating part, it is necessary to collect the dynamic parameters of the rotating part in the high-speed rotating state in real time. How to supply power to the test circuit on the rotating part is one of the main technical difficulties currently faced. [0003] At present, the power supply used in the data acquisition system of rotating parts at home and abroad mainly includes slip ring power supply and battery power supply. The slip ring power supply uses the elastic pressure of the brush to make sliding contact with the conductive slip ring groove to transmit signals and currents. It is suitable for applications that require unlimited, co...
