The Energy Factor in Induction Heating Systems

SummaryThis work gives answer to an important questian usually asked in induction heating designs: given a coil and a workpiece. which are the optimal: parameters (frequency and coil-workpiece geometry) to heat this system? TO answer this question a new parameter called Energy Factor (EF) is defined in electromagnetic and in circuit terms. This factor indicates the transfer energy efficiency between two systems (Fig I), in the case of an induction heating system, between the coil and Me load.
