Poida posted something similar when he was investigating Dead time and switching waveforms around 4 years ago, in "Various aspects of home brew inverter", dam time fly's. Inverter and toriod but only 2000uF DC filtering, No Load. 50V Rail. Incorrect Chokes (rough test setup) waiting for two cores. DSO Traces, apology for dim colours. Blue: Bridge out to Toriod. PINK: HI side Gate and source. Yell: LO side Gate and source. 2X Standard CRO Probe connections (Not ideal or even good but, whatever) Pink is 100mHz differential probe. Other channels bandwidth limited to match.   .
