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： The invention consists of an apparatus for industrial induction heating applications fitted with an inverter with a control system enabling a considerable reduction in the transistor losses. The converter consists in a three-phase diode rectifier (1), a full bridge inverter (2), a series resonant output circuit with a matching transformer (3) and a control and auxiliary items block(4). The switching frequency of the inverter automatically adapts to the resonant frequency of the load enabling ZCS (zero current switching) switching for any load situation. An output power control system, based on Pulse Density Modulation (PDM), continuously regulates the output power, maintaining the ZCS mode. Appropriate management of the dead time of the driving pulses of the inverter transistors ensures Zero Voltage Switching (ZVS) operation. The maximum output power of the inverter, when running at high frequencies, is obtained with modulation index values below one.

摘要： System and method for induction hardening of metal rings, which comprises: two heads, each of which is attached to an induction medium; a system for vertical approximation of the two induction media to the metal ring; a system for horizontal approximation of the induction media to walls of an internal surface of the metal ring, and an oscillating circuit, where the system is configured so that: the system of vertical approximation displaces simultaneously in a vertical direction the two induction media until they are introduced into the metal ring; the system of horizontal approximation separates the two induction media from each other in a horizontal direction to bring each induction medium closer to the walls of the inner surface of the metal ring to heat it for a pre-established time, and to displace vertically the two induction media simultaneously until they reach a shower position to obtain the hardening of the metal ring.

摘要： The invention consists in the development of tempering systems which have a cylindrical symmetry without the piece to be tempered having to perform any movement. The system is capable of performing a rotational movement of the assembly formed by the secondary winding of the output transformer (5) and the inductor (3) about its longitudinal axis of symmetry and a displacement along the same axis. This movement is performed while the energy necessary for tempering a piece by means of induction is being transferred. Energy transfer is performed without the presence of mechanical contacts by means of a magnetic field, i.e. is performed by means of physical separation between the primary winding (4) and the secondary winding of the output transformer (5) with a rotating movement.
