Highfrequency induction isoparametric log
WebThe solution is the use of a dual-frequency inverter. The output current i flowing through the exciter coil consists of two components: i = iMF + iHF (MF, medium frequency; HF, high frequency). Properly matched frequencies and amplitudes of both iMF and iHF allow to reach even heat surface distribution. WebAnswer: Induction heating is achieved by inducing eddy currents into the product being heated (or for induction cooking, into the vessel in which the product is contained). The …
