Dear friends,
I need one help on this topic, please.
two rectifier diodes 6A4 are connected in parellel and it is connected in seires with a high speed AC motor(22000rpm) to reduce the speed with a switch arrangement.If we put switch in one direction the motor will be directly connected to the line and in other position it will connected through the diodes.
Now these diodes are failing frequently , will you able to suggest a reason and remedy for this problem.Motot input voltage:230V
max current : 5A
Diode no : 6A4 / 400V PIV/ 6A
waiting for a positive responce
