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.
