HV isolation DC/DC conversion - please help

JT · 2005-08-08T23:02:57+00:00

I have here the highest isolation DC/DC converter IC I could find: the6kVDC isolation DC/DC converter NMS0515 (5Vin, 15Vout, 67mA output),and it's giving me a headache.I need 15Vdc and about 100mA with 30kV isolation from the input. Thething is, I will only need that type of isolation for 100us at a 1kHzrep. rate. Analogous to Peak power vs. RMS, is there not some finiteelectrical break-down time required? How does it scale?Thanks,JT

You can do better with a motor-generator set with a long plastic shaft. The head light's light decreases as the square of distance but the losses in a shaft are only linear with distance.
