High Voltage Switching Application

Recommended Posts

I have small switching problem for a DC/DC converter. Basically, I have two 1500V DC converters that take 0-5V input and individually feed 2 high voltage actuators. When the input is less than 2.5V, I need the outputs to be  1-1 : 2-2 (converter 1 to actuator 1 : converter 2 to actuator 2). When the voltage is above 2.5V at the input, I need a 1-2 : 2-1 configration. The problem arises because I have to switch on the high voltage output side of the converters. I have acess to 1500V transistors, but have never reallly used them in a swtiching application. Weight is a very hard contraint in my application. Can anyone help me with this? Thanks.
