How do I add plot windows in which all get a vertical scale at the same time?

  Clearly this is an example circuit.  The 82% DC @ 10kHz should result in a current increase up to ~2.3A, but the 700V flyback sucks all the current out.  I was expecting that the flyback would be positive and so clamped by the HSD body diode to the 13V rail.  This circuit works on the HIL but not in simulation.

Whilst I'm on the topic of questions, where is the "post" button?  It seems that my option is 'Reply'.

Hi MikeyG63 

I'll have to see why your axes aren't showing. They should. The Reply button is essentially "Post Reply".

Not sure about the circuit performance. Will look at that.

Hi MikeyG63 ,

Can't run without your models and subckt. Zip everything up and drag to reply window. If you have a schematic, send that too.

Curiously, exactly the reverse.  The protected HS is just a safety switch IFX BTS7040 with a 35V clamp zener that turns it on in the event of negative transients.  It worked in simulation then got toasted on the HIL.  Hence, now it has a TVS SMBJ24CA across it.  Only the LSD is on a PWM channel to be used for peak and hold current control.  The PMEG40T50EP Schottky model is in the zipfile along with a 'Draft3.asc' as the simplest demo for only one Y-axis at a time.  The last and hopefully useful model is a Variable Frequency, variable duty cycle PWM source.  It's created using maths and behavioural sources because I am frequently trying to control peak and hold solenoids and "Ton" appears to be the only parameter of a complex Voltage/Current source that won't take a variable.  And if you can tell me why "Bosch Tank Valves Peak and Hold 10kHz meas open loop" runs as slow as it does, then brownie points from me.  I don't think it's my PWM source as I can strip that entirely out without much improvement.  I'm also puzzled as to why the green 'Run' arrow and red 'Stop' box are now greyed out, along with the scope probe for a voltage net plot and a current probe for a current plot?   Thanks for reading this far, and your assistance!  Regards, Mike.Peak & hold HS LS.zip
