ABSTRACT

In order to solve the problem of excessively thin and overpower of ordinary medium frequency induction furnace lining, a main circuit with high Q-value and anomalous power characteristics is designed. It is applied to the field of induction heating, which can effectively increase the lining thickness, reduce the steel consumption, and will not bring high working voltage, working current and low efficiency, realizing the converting circuit of virtual work to the real work. The high the Q-value is, the more the abnormal power characteristics of the output power are. The main circuit effectively overcomes the difficult vibration of traditional parallel compensation circuit and the over-voltage of the power supply in series compensation.
