This started with my question here there is no need to read it, I put it here for additional info.
I'm trying to drive two MOSFETs in Half-Bridge topology and I finally could get the pulse transformer working correctly using a IR2110 working as a two low-side driver. Here is the schematic:
Probe 1 and
Probe 2 are my oscilloscopes probes and here are the resulting waveforms when driving the IR2110 through a microcontroller generating a 200KHz Half-Bridge PWM:
There is some ringing but I assume that's because I'm testing in a protoboard and there is a lot of distributed capacitance. My real concern is about the waveform. The transformer in the schematic has only one secondary but my transformer has two secondaries in opposite directions for each MOSFET.
The yellow waveform is
Probe 1 as you can see I get the expected waveform with a dead-time at the reference level (the small '1' yellow mark on the left of the screen) but on the secondary side (the blue signal,
Probe 2) this dead-time is at about 10V and it should be at reference level otherwise MOSFET is active at 10V.
Am I right or I'm missing something?
