ZVS Induction Heater help? Answered
Hi, I tried to build a ZVS induction heater using this circuit http://img413.imageshack.us/img413/5136/inductionm.jpg , but I had no sucess. The work coil is 10+10 turns of 22 AWG wire around an old highlighter casing, and I am powering the circuit from a working 12 volt 7ah battery. The circuit works with my flyback transformer, but does not work on the induction heater. I am using all of the standard components in the flyback circuit, but I replaced the 5+5 turn primary with a 10+10 work coil. As far as I mesured with my thermometer the temperature of the object never increases over 1 degree (I am trying to heat copper wire or a small picture nail).
Does anyone have some suggestions?
Edit: Sorry about the delay, but I was able to heat a large paper clip using 8+8 turns of 16 AWG wire wrapped around a glass test tube. This time I used a huge 24 volt center tap 18 amp transformer to get 12 volts.
