Abstract: An induction heating system is disclosed. The system has an electrically conducting load and an inverter circuit with a switching section and a resonant section, wherein the switching section can generate an AC current from an AC input voltage incorporating a plurality of half-waves. The resonant section has an induction heating coil adapted to receive the AC current for generating a corresponding time-varying magnetic field in order to generate heat in the electrically conducting load by inductive coupling. The amount of heat generated in the load depends on the electric power delivered to the load through the induction heating coil, which depends on the frequency of the AC current. A method for managing an induction heating system also is disclosed.

Abstract: A brake caliper for disc brake has two side walls, one on either side of a brake rotor or disc. Each of the side walls has at least one seat which receives a brake pad having a friction surface which engages the disc, and a thrust surface opposite the friction surface. A brake piston engaging the thrust surface of the pad pushes the pad against the brake disc. The caliper has cooling ducts for conveying a flow of cooling air to the pad. These cooling ducts comprise a first outlet port that is configured to generate a first partial cooling flow on the side of the friction surface of the pad and a second outlet port configured to generate a second partial cooling flow on the side of the thrust surface of the pad.

Abstract: A brake caliper has two spaced side walls, one having structure for fixing the caliper to a vehicle. The side walls are interconnected by structure which extends astride the disc space. Each of the side walls defines at least one seat for accommodating a pad having a friction surface to engage the disc and a thrust surface opposite the friction surface. The caliper thrust means that are suitable for engaging the thrust cooling ducts for conveying a flow of cooling air to the pad. The ducts have a first outlet port that generates a first partial cooling flow on the side of the friction surface of the pad and a second outlet port different from the first outlet port and configured to generate a second partial cooling flow on the side of the thrust surface of the pad. The second partial cooling flow is different from the first partial cooling flow.
