Improvement of the power factor correction in machine tools
An actual problem of the efficiency in machine tools is investigated by the improvement of the active power factor correction. An analysis of one method of the active power factor correction in machine tools is performed. A development of the active power factor correction is offered on the basis of the reduction of the power recovery in an infeed/regenerative module and the expansion of the dc link. The power factor correction in a machine tool is explored by means of experimental measurements and simulations of the electric system in a machine tool.
