I have a Keysight N5771A which goes up to 300V but the response time is not fast enough to be used for the load dump test. So I use it to supply the 202V and another power supply to supply the 24V. Here is the circuit:
- Does this circuit work? I do not want to blow up the lab and the Keysight PSU (rental equipment).
- What do you suggest to use for the diode and switch?
- Is it ok to build this circuit just using flying wires or it need to be fixed? Can I use a breadboard?
