Hi.
We switch a series LC-load in a 600V H-bridge.
Today we measure the current using a transducer (LEM HO- series)
I wanted to try to use a shunt instead. So connected a shunt in series with the load.
Connected a AMC3302EVM board, connected 5V power to the board and measure the output.
At 16 kHz I had about 100A of current (Says the HO) in a nice triangle wave.
But the output of the EVM board shows an almost square wave.
Now I wonder where I was wrong. Clearly I am wrong somehow.
So I am thinking that perhaps the AMC3302 is wrong for this. Looked good but not designed for this application.
or
I have made an error in my setup of the EVM board. Not much to connect but still managed to get it wrong..
or
I am completely wrong about the current being triangle shaped.
