Hi...
I've two DC generators, namely Generator-1 and Generator-2.
When the Generator-1 supplies 1.5A, the output current waveforms (see attached figure, measured using Tektronix TCP312 current probe with AC coupling) shows peak-to-peak current ripples of 40mA. The frequency of the current ripples is about
When the Generator-2 supplies 37mA, the output current waveforms (see attached figure, measured using Tektronix TCP312 current probe with AC coupling) shows peak-to-peak current ripples of 8mA.
The frequency of the current ripples is about 200Hz
Kindly refer to the circuit as shown in the following link:
EEVblog #102 – DIY Constant Current Dummy Load
Will the current ripples be eliminated or reduced if the positive output terminal of the generator is connected to the "constant current dummy load" presented in the EEVblog #102 (see attached figure on setup).
Well, the circuit may need little modification. For example, the "1R" need to be replaced with a proper value to optimise the current measurement range.
Kindly advise.
Thanks
