    A variable speed drive, which includes a prime mover driven alternator, a 36-SCR cycloconverter, and an induction motor, is simulated on a digital computer. The induction motor model is developed to permit a general solution when any number of the stator currents is zero. Using conduction criteria for individual SCRs, a new cycloconverter model is derived which results in an input/output transfer ... View full abstract»
