You don't want to use the standard chopped waveform controllers on a PowerMaster or a TIU, as the logic assumes a sine wave as input. Using the Z4000 with it's synthesized sine wave works fine, I should have taken a picture of that when I tried it.
As you can see, even at full throttle, the chopped waveform transformers don't output a decent looking sine wave. In an interesting twist, if you have a brick feeding a TIU and set a variable channel to full throttle (22V on the display), you will get a pure sine wave out of the TIU.
