The second edition of the Handbook of Induction Heating reflects the number of substantial
advances that have taken place over the last decade in theory, computer modeling, semi …

This paper presents a phase angle control method of high-frequency resonant currents in a
zone-control induction heating (ZCIH) system, which consists of split working coils and …

This paper proposes a new “zone-control induction heating”(ZCIH) system consisting of two
or more sets of a high-frequency inverter unit and a work coil. The work coils are wound …

The induction surface hardening of parts with nonuniform cylindrical shape requires a
multifrequency process in order to obtain a uniform surface hardened depth. This paper …

The advent of dual-frequency induction heating (DFIH) technology has revolutionized
modern industrial applications by providing flexible regulation of the heating process …

Recently dual frequency induction heating is often performed for hardening an uneven work-
piece such as a gear which has tips and bottoms, and two resonant inverters are necessary …

This paper presents the development of a simultaneous dual frequency (SDF) induction
hardening apparatus for gear hardening. First, a 2-D finite-element (FE) modeling for a …

This paper proposes a new" zone controlled induction heating"(ZCIH) system. The ZCIH
system consists of two or more sets of a high-frequency inverter and a split work coil, which …

This paper presents new resonant inverter topologies for dual-frequency induction heating
(IH). These 2T1C and 3T topologies combine the advantageous features of two-and one …

Parts of certain objects need hardening. Hardening is a heat treatment process which can
be achieved by induction heating. Certain objects like gears require alternating source with …
