### Excessive current in this inverter design

I made this inverter with Proteus. The phases have no load at all, but the input current is very high (red arrow.) This happens only when capacitors marked by the green arrows are connected. They ...

### Issue with H-Bridge simulation waveform

I've built a simple H-bridge circuit with LTSpice: DirSigA (blue), DirSigB (red) and Vout (green) waveforms: DirSig A and B are both pulse signals with a Vmax of 5v. I've been tinkering with the ...
