A power meter for wireless power transfer system
« on: February 02, 2023, 11:14:02 am »
Hello Guys,
For me, is needed some opinions about my project. Currently, I'm thinking about designing an embedded system for wireless charger high frequency primary circuit power monitoring then SS compensation topology is being used in charger. I'm thinking about using shunt for current measurements, because max ac voltage would be 1V and max current 1A. What do you think about that? Signal bandwidth 200khz

2 % accuracy for power. Bandwitch 200khz. Voltage 0.1-1V, current 0.01 - 1A
