Question	—	208VAC triple-phase to single-phase conversion The question: Is there a way to convert from triple-phase 208VAC to single-phase 208VAC? Background: Hi everyone, I am stuck on a project I'm working on. I'd like to convert 208VAC (three phase, NEMA L5-20R) to 230VAC (single phase, NEMA 5-20R) for use with a piece of 230VAC equipment that pl... (more)	—	over 2 years ago
Question	—	PTC resettable fuse leakage current Intro Hi everyone, I have a question about the practical use of a PTC (positive thermal coefficient) resettable fuse. I've never used one before, but I'd like to add one to a DC motor circuit to prevent it from overheating when running continuously. More features being used I already have two mo...

Answer	—	A: Critically damped oscillation issue I don't know how to attach images to a comment thread, so I will just open up an answer for this. I redrew the schematic for you to reference. Image alt text I think that symbol at the top of your drawing probably represents a switch. We are likely looking at damping when the switch closes. We ... (more)	—	almost 3 years ago
Question	—	Trouble understanding how to use adjustable LDO regulator The question being asked Ultimately, I want to know why the output voltage wasn't the expected (via calculation) 11.72V when the estimated drop-out voltage at the 0.1A load was about 200mV. The input voltage to the regulator was 12V. Hi everyone, first off, I wanted to say I am a big ... (more)	—	almost 3 years ago
