Noise in the output of inverter

[pkbrq]

Hi all,
I am tesiting a full bridge inverter with LCL filter. I am getting noisy waveform at the load (R = 300ohms).

The yellow one is load voltage while the green one is voltage across capacitor.
Switching frequency of inverter is 50khz. The filter used is LCL filter (L1 = 12.4mH(inverter side inductor), C = 8.99uF, L2 = 4.4mH(output side inductor))
Could someone please explain why I am getting this kind of noisy waveform and How can I remove the noise from the output?

Does your system switch off current through a coil by making it see high impedance suddenly? It needs to continue to generate current. High voltage spikes can result. These are probably the noise on your waveform.

It might be solved by a snubber network across your H-bridge. Possible a resistor and capacitor in series.

Hi BrodtheRad
Thanks for the reply. But there is no coil in my system where a current is abruptly stopped.
