Stories from the rotabench lab: >>Let them (almost) burn!<< The title picture is a photograph of the setup for testing the “freewheel” diodes on the rotabench 6P lab-inverter power stage. The purpose of this experiment was to find out, how much “reverse current” the power stage can handle in a fault condition. The experiment was …
Do I really need that much equipment? obviously yes. With this setup, I can measure the group delay of the analog inputs for the voltage and current measurement of the rotabench 6P inverter. The calibration process has two steps: in the first step, the outputs of a simulated PMSM are fed into the inverter. The …

Hot on the bench: Signal Conditioning PCB for LEM CT-200 current sensors. I just finished soldering the first samples of my signal conditioning PCB for LEM CT-200 current transducers. These devices converts the current output of up to 4 current CT-200 transducers into a voltage. For high precision I use Vishay Z-Foil burden resistors with …
