It is time to test our revisited VFD PSU in real life. We are going to build a quick prototype using a PCB from MVFD 16S7D Panel with minimum components loaded. All we need to solder is a VFD controller IC2 (instead of HT16515 we are going to use PT6315 as they are pin-to-pin compatible), […]

We are continuing our experiments with an alternative VFD power supply which we started some time ago. The high voltage part remains pretty much unchanged for now – it is an inverting regulator based on inexpensive chip MC34063. Excessive current consumption (60-70mA) in idling mode is still an issue but we are not going to […] |
