Measuring Capacitor ripple current
Measuring Capacitor ripple current
(OP)
Hi,
How can I measure the ripple current through a capacitor? Can I just use an ammeter?
Thanks

So try measuring temperature rise of those high frequency caps rather than the actual ripple current. Also, any current measurement will need to be a true RMS measurement to be meaningful, ripple currents are almost never sinusoidal.
As electricuwe says, inserting something in the current path can be very difficult and often misleading, especially on a compact multilayer circuit board.
