DEVICE FOR FORMING AC VOLTAGE FOR POWERING METAL INDUCTION HEATING APPARATUSES

摘要

A device for forming AC voltage consists of four transistors connected into a bridge circuit, in whose AC circuit a parallel resonant circuit is connected built of a balancing capacitor and an inductor. Additionally to the transistor bridge two accumulative chokes and two by-bass diodes are connected in corresponding manner, which form together with first and third transistors two pulse regulators.
