I need to stabilize a DC current of 600 V

[lozano2]

I need to stabilize a DC current of 600 V. It's a circuit that generates a DC current in amperes and current unstable. The current is 60 A How could stabilize the current?

Are you saying this is a current source power supply? I realize that English is not your first language, but we need a better description...

Yes, It is a current source power supply

Is your load varying rapidly?

Please give all description you can of the entire circuit. A schematic would be best. If you are designing this power supply, there will be others on this board who can offer ideas, but "unstable" is not enough information.

- It is a circuit supply where varies the current and voltage (the voltage is approximately 637 V but has variations over time).
- The current is about 1.06 A, with small variations in time
- The load requires that V = 600.

And the load is????

Sounds like you need a voltage source, not a current source.

I'm working with a DC bus where I want to feed the 600 V, which is part of an electronic circuit downstream. The load is adapted to the power output of the voltage source.

Thanks

Need more information.
What is the load?
What is the power source for the bus?
There is a big difference in stabilizing 60 Amps compared to 1.06 Amps.

Right now, we have no idea what your circuit is.

A current regulator with an inductor output filter does a decent job of providing a stable current. A voltage regulator with a capacitor output filter does a decent job of providing a stable voltage.

It sounds like you have the capacitor output filter (the DC bus) but you still need the voltage regulator. There are a number of ways to build the required regulator. Many of these depend on the unregulated input voltage vs the required output voltage.
