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 […] The need in inexpensive, simple and compact power supply unit (PSU) for VFD projects has always been topical for us. MVFD 16S8D Panel was designed to address the challenge, however, as it always the case for first revision, there are some things which require improvements or rethinking. And MVFD Panel was not an exception in […] |
