Figure 37 shows a three phase, three step, half wave motor
controller. This configuration is ideally suited for
automobile and other low voltage applications since there is
only one power switch voltage drop in series with a given
stator winding. Current flow is unidirectional or half wave
because only one end of each winding is switched. The stator
flyback voltage is clamped by a single zener and three
diodes.
