ZVS Induction Heater – Original

For now this is just a collection of some links and notes.. I have built in the past and plan to rebuild in the future a large multi KW induction heater, but alas too many project syndrome. Build your own: https://markobakula.wordpress.com/power-electronics/500w-royer-induction-heater/ Or buy for $8.55: http://www.banggood.com/5V-12V-ZVS-Induction-Heating-Power-Supply-Module-With-Coil-p-1015637.html
