An analysis is made of the SCR chopper for the control of traction motors. The analysis divides the chopper period into several sub-divisions, the dynamic circuit equations for each time interval are derived and an on-line digital computer is used to determine the complete solution through an iterative process. Computer simulations over a wide range of possible design conditions are summarized. The results compare very favorably with test data from a prototype system.
