Thyristor cascade speed control circuit


Posted on Mar 28, 2007

Circuit shown in Figure 3-170. Wound rotor induction electric motive at different speeds induced in the rotor voltage (turn difference frequency EMF) U. A s U, o (Us0 is sl when the rotor open circuit voltage). The three-phase voltage through a bridge rectifier

into a DC voltage UD, UD and then by the inverter to AC inverter power, the inverter transformer feedback network. Then the inverter voltage Up can be viewed as added in the rotor circuit EMF. Inverse control variable inverter angle Lu, you can change the size of Up in order to achieve speed control.
