If you\u2019re like me, you\u2019ll have many wireless charging coils around your lab for various standards. They likely entered your lab well-dressed; adorned in well-labelled packaging, which told you exactly the value of its inductance, resistance, and current rating. But, perhaps, the coils were having a lot of fun in the lab, and the well-labelled packaging that was once their home is now nowhere to be found.<\/span><\/p>\n

\"unlabeled \u00a0<\/span>\"\"<\/p>\n

Or, perhaps, it\u2019s another glorious day in your lab; you have lots of ideas and are ready to do some prototyping. But the next-day delivery just isn\u2019t quick enough when you need to prototype <\/span>now<\/b>. The only thing you can prototype some wireless charging with right now is some enameled wire you\u2019ve been using for your PCB re-work. <\/span><\/p>\n

How will you determine the coil inductance for your unlabeled coils or your DIY enameled hack? You, my friend, may be looking for an <\/span>LCR metre<\/span><\/a>. <\/span>Or are you?\u00a0<\/span><\/i><\/p>\n

Some LCR metres struggle with detecting <\/span>millihenries<\/span><\/a>, let alone microhenries. Having the right one can be an investment. Don\u2019t get me wrong, an LCR metre is a piece of equipment that nobody would complain about having in their lab. Being stuck with this problem without an LCR metre can mean that calculating the receiver coil inductance becomes a complicated process requiring multiple pieces of equipment like an oscilloscope and a separate signal generator. But what if you have an ADP3450?<\/span><\/p>\n
