    摘要： An induction heating apparatus comprises a rectifier circuit (1) at its input, connected to the electric mains (2), an intermediate energy storage device, a single inverter circuit (3), a single resonant output circuit (4), a single heating inductor (5) and a block for auxiliary supply, regulation, supervision, display, cooling and communication (6). The single resonant output circuit (4) with four reactive components is able to generate a resulting current produced by simultaneously superimposing two current components with different frequencies. The power of each of the two different frequency components present at the output of the single resonant circuit (4) is regulated independently. The resulting current feeds the single heating inductor (5), generating a magnetic field allowing for special induction heating/hardening of complex surface parts such as gearwheels or sprockets. Some inverter semiconductors are of silicon carbide technology (SIC) devices.

    摘要： An induction heating converter whose input is connected to the electrical mains (1) and which has at least two inverters (3,4) supplied by a single voltage source, whose outputs are connected to a resonant circuit (5) of at least three reactive components able to generate a current produced by simultaneously superimposing at least two different frequencies. This current supplies a single coil in order to generate a magnetic field enabling multi-frequency induction heating processes. The converter has a block for auxiliary power supply, regulation, supervision, display, cooling and communication (7). The proposed system enables independent power regulation of each of the different frequencies. It can be applied, amongst other uses, to induction heating of complex surface workpieces such as gearwheels or sprockets.
