Shazahn PDF This gives you the basic idea, but there are other problem issues not mentioned here. You need to be a member in order to leave a comment. We need to create a additional leakage path greater that the worst leakage spec in order to balance the voltages. Also note that we will be generating a fair amount of heat in the balancing resistors as shown on the wattmeter.

We connect dagasheet as shown in the first diagram, but find that the load turns on when we connect the power, even with no trigger applied. Posted June 6, This will cause voltage breakdown of D1, followed by breakdown of D2. If we take 3mA to be very safe, the voltages balance out but we have to live with the high leakage current through the load, which may be a problem for the application.

From what I have seen they use pulse transformers to trig from a lower voltage to achieve simultaneous response. Sign in Already have an account? Posted June 3, We can see that D1 with the lowest leakage will have more than its rated V over it. Most Related.
