“…The shorter startup and shutdown times lower workers cost [11]. The induction heating has also improved industrial processes as the consistency and repeatability of the heating process improves the quality and increases the productivity; it is a contactless heating process where the target is not affected by being in contact to the heating element [12]. The induction heating is also seen to be more clean and safe as the magnetic field heats directly the target, whereas the temperature of the surrounding area is lower, also avoiding surrounding materials [12].…”

Abstract. In the study an industrial occupational setting was investigated in order to determine the workers exposure to the magnetic fields from induction ovens and to develop risk mitigation procedures to lower the exposure. Electromagnetic field measurements were conducted and the workers exposure to the electromagnetic fields was assessed in the framework of the new occupational electromagnetic field legislation. The results show that the exposure could be significantly reduced by implementing relatively easy mitigation measures, including workplace rearrangement, work procedure redesign etc. Time-weighted average exposure to the magnetic field could be lowered from 2.57µT (maximum observed procedure case) to 0.12 µT (recommended procedure scenario after interventions). The investigation also revealed that little attention is paid to training the workers who may be affected by high levels of electromagnetic fields. Considering the requirements of the new European Union and national electromagnetic field legislation, immediate planning of appropriate schooling programs is necessary for all parties involved: employers, workers, work environment specialists.

“…Increases in operating frequency have been the result of improved semiconductor device technology and elimination of switching losses by means of soft-switching techniques. Various devices, such as power MOSFET's, SI thyristors, and static induction transistors (SIT'S), applicable to high frequency and/or high-power induction heating systems have been reported in the literature [5]- [8].…”

Abstract-This paper deals with design and analysis of Zero Current Switching (ZCS) resonant inverter based high frequency induction heating. The basic circuits consist of a half bridge inverter and an induction heating coil. This equipment works on the principle of eddy current induction. The high frequency current is given to the coil which acts as a primary winding of the transformer. The work piece acts like a short circuited secondary of the transformer. The heating effect is obtained by the eddy current induced in the work piece. Since eddy current is proportional to square of the frequency, heating effect will be high at high frequency. The heat can be varied by varying the frequency. When high frequency in the range of several hundred kHz is used, the switching losses will be more. To reduce the switching losses ZCS soft switching is employed in this work. Simulations are performed in MATLAB to understand the working of ZCS based high frequency induction heating. Also, hardware results are obtained using ZCS IC UC3865N.

“…Today they are widely preferred in industry for pre-heating, post heating, melting, forging, sealing, fastening and the cementation of metals [2]. Induction furnace manufacturers also state that the equipment is used in various applications such as hardening, tempering, soldering, normalization, rectification, power production for plasma applications, food packing, shrinking, glass and wool fiberization, in line heat treatment and the hardening of large rings [3].…”

Original scientific paper In this study, an induction air heater prototype that is designed to supply hygienic air was analysed. The purpose of this paper is to determine the distribution of energy losses and investigate the effects of inducer discs on the thermal efficiency of the prototype. The analysis was carried out by applying the 1st Law of Thermodynamics. In the study, the natural convection and radiation losses, the discharge losses and the losses due to kinetic energy were calculated and presented. The maximum thermal efficiency was calculated to be 29,9 % without discs. It was seen that, to ensure the competitiveness of the induction air heater among other air heaters, the thermal efficiency can be boosted up to 90 % with appropriate insulation and construction. It was seen that utilizing the discs decreased the efficiency and the total energy loss was reduced as the number of discs was decreased.
