| MOSFET turned off - strange voltage drop |
| << < (3/3) |
| tester43:
Hi, Is this because if bridge not being loaded with MOSFET closed then the whole PCB + wiring works as a capacitor for the circuit? Or is it different effect? |
| StillTrying:
Yes, when the bridge rectifier and everything else has stopped conducting at 0.8V, it's just a floating voltage on the stray capacitances. The first opto could be replaced by 3 resistors, one from each AC connection, and one to 0V. |
