impadance mathing and pwm circuit
« on: April 28, 2009, 06:54:10 AM »
Hallow friends
I have en electrical device that work white 110 volt and 50 ampere AC my driver burned because there is volt and current that return to the driver   
I search after an electrical circuit that absorb the return current
I can't use diodes because I have AC current (not DC current)
This problem is attached to Transmission Lines
Maybe the circuit solution use coals or impedance matching
If anybody have a good site to buy this or to understand this I will glad to know
Also I have another problem that I need to design a pwm circuit
