Thyristor leonard device with field controller

阅读:221发布:2022-02-14

专利汇可以提供Thyristor leonard device with field controller专利检索,专利查询,专利分析的服务。并且PURPOSE: To determine the rated voltage of a DC motor without considering power supply conditions by varying the armature setting voltage of a field controller in proportion to a main circuit power supply voltage at constant output controlling time.
CONSTITUTION: A thyristor Leonard device 1 controls a main thyristor converter 13 in response to the deviation of the output voltages between a speed setting potentiometer 7 and a tachometer generator 6 and deviation between the previous deviation and the output of a current transformer 11. A field controller 2 controls a thyristor converter 21 in response to the deviation of the outputs between an armature voltage setting potentiometer 14 and an armature voltage detector 16 and deviation between the previous deviation and the output of a field current detector 18. The power of the potentiometer 14 is supplied through a transformer 27 and a rectifier 28 from a main circuit.
