Hi. I was just wanting to run this by someone else. WHen you place a current sensor in series with the H-bridge you measure the battery current going to the H-bridge, while when you place the sensor in series with the motor you measure the current going through the motor right? So the motor way lets you measure the current in the motor at all times (including flyback when zero battery current is flowing so you don't need a lowpass filter), but you do need a low pass filter when using the H-bridge way right? Since there will be times (when the transistors are off) that the current will read zero?
I haven't seen too many schematics of bridges like this, so I'm just wondering if they always stick a low pass filter on the current sensor if it's in series with the H-bridge.
