A Reversible Smooth Current Source with Momentary Internal Response for Nondissipative Control of Multikilowatt DC Machines

Abstract
A dc machine drive in the form of a reversible source of almost ripple free current is presented. The internal current source mechanism is suited for the submegawatt range and responds at most within 50 psec to externally applied commands. Static characteristics and the dynamic conditions during internal current reversal and the therefrom resulting effects of machine behavior are presented. The advantages of the system are the appreciable speed of response, the therefrom derived improvement of dynamic stability and the low cost of production.
