I support the idea that the diodes are intended to keep the field pointed in one direction when the armature is reversed, so that torque and rotation will reverse, is supported by the clip from audel's of a series motor controller below. The diagram describes a reversing 5 step drum contr...
Understanding of operation principles of cyclo converters should begin with single-phase to single-phase cycloconverter. This converter is having back to back connection of two full-wave rectifiers. Suppose for getting one-fourth of input voltage at the output, for the first two cycles of Vs the ...
