Hi,
I am a designing engineer.I am currently working on A grid tie based solar inverter.My system is capable of driving 1650w load.Having an output of 350v dc with 4.72 A rated.i am using push pull transformer for my design.The problem i am facing now is that when i check the output of the bridge rectifier after output i got a clean waveform of pulsed dc of 400v peak.That seemed ok but when i connected an induct or in series to it, i saw the output of bridge rectifier shooting to 1400v peak.I happen to see severe ringing.Why is that so?will an inductor cause such a heavy ringing especially at the output of bridge rectifier? Is it the material or the type of induct or chosen a reason for this kind of heavy ringing?
The out of the bridge rectifier with just bridge rectifier and with l connected is being attached below.
