CONNECTION FOR SWITCHING TRANSISTORS' BRIDGE COMPENSATION FOR INDUCTIVE LOAD BONDING

摘要

The connection serves for feed-back compensation of the bridge of switching transistors. The compensation is controlled by the signal with pulse-width modulation and it is used especially for supplying of direct current servo-drives of the average power between 100 and 500 W. For connection of the inductive load, the connected compensation is used and it safeguards the correct activity regime of the switching transistors of the bridge. Its merit lies in the fact that the first terminal of the first compensation winding of the choker is connected to the joint link of the first terminal of the second resistance with the cathode of the second coupling diode and of the collector of the fourth switching transistor, while the second terminal of the first compensation winding of the choker is connected to the base of the third switching transistor and the first terminal of the second compensation winding of the choker is connected to the joint link of the first terminal of the first resistance with the cathode of the first coupling diode and of the collector of the second switching transistor, while the second terminal of the second compensation winding of the choker is connected to the base of the first switching transistor. The connection can be used especially with industry technological machines in mechanical engineering and electric industry.<IMAGE>
