It looks like an AC voltage booster circuit to me. The diode D1 is blue in color, small glass type. Q1 couldn't be traced either because the print was scraped of by the manufacture.Only its pin#1 and pin#3 responded to the DMM, it read zero like a dead diode, pin#2 does not read with any other pin at all. Pin#4 which is the tab is also unconnected.just cannot figure out the device or its specs. It got broken while dismantling the glued circuit. The diode polarity and the value is not certain but this is its place in the circuit. I disassembled it carefully because D1, R1, R2, C2 and Q1 are obscured inside a glue like paste.ĪC IN is from a small 650VA Generating set which is normally incapable of powering the connected loads. The folks call this an alternator power booster! It enables small gensets support loads bigger than their coils and feel alright with it without yearning! Swagatam Majumdar, you can build a better device that can perform this same thing without depending on their own construction. I only hear about this type of device here in Nigeria. Anyway I uploaded the picture here! see the circuit and find out what these our Nigerian Guys are up to. Please direct me I can sent this through Homemade Circuit. I didn't see how I can upload picture there. I want to show you the circuit through Homemade Circuit or Brighthub. There is this circuit I want to show you.
