Electronic Switching Circuit between high voltage sources(larger than 60V)

[Tarek Abu ElSauod]

Hi there

Peace on you all,

I need to design an electronic switching circuit to switch between high DC Sources(range from 30 to 80V) to form a square wave from these DC sources.Up time and down time i need to get control of them with very small switching time from up to down and viceversa (like ideal square wave, u know). You can at least guide me to quick sources to design it myself.

Thanks in advance

Up time is about 100us

What current you plan to switch ?

I didn't get it what u mean although, i mean to switch between DC Sources to form +ve high level and zero level with definite periods. There may be a way that only one source is needed to do the job and switching it on and off.

any help ??

The question is, what is the maximum current that will go through this switch? What is the minimum load impedance?
