Adaptable cooking surfaces are at the forefront of design trends because of the many advantages offered to users. These improvements and advantages have their counterpart in the increased design challenges related to inductors and power electronics. Shifts in the relative position between the pan and the inductor may cause the inductor to be totally or partially uncovered, leading to changes in the...
Collaboration between Industry and University is becoming more important in order to improve the competitiveness of the research and development activities. Moreover, establishing synergies to bridge the gap between the academic and industrial spheres has demonstrated to be advantageous for both of them. Nowadays, Industry is moving towards an open innovation structure, in which external agents as...
Designing the converter for an induction cooker, the main difficult lies in the variability of the load, due to the wide range of vessels available in the market. Such issue is equivalent to the problem of identifying the vessel's properties. In this paper an identifying method of such properties is proposed with the objective of system-level simulation and design. The method is based on a combination...
The development of ad-hoc control architectures is a time-consuming task which is often required to design and evaluate power converters. In this paper, an FPGA-based versatile control architecture test-bench which enables to evaluate and implement different control strategies applied to different power converter topologies is proposed. It is based on a hardware/software codesign by means of MicroBlaze...
In this paper, a method to improve efficiency in half-bridge series resonant inverter applied to domestic induction heating is presented. Low and medium output powers required for this application implies the use of higher switching frequencies, which leads to an efficiency decrease. Asymmetrical duty cycle (ADC) modulation scheme is proposed to improve efficiency due to its switching frequency reduction...
Integral expressions of the equivalent impedance of flat-type coils for induction heating systems are derived. These expressions are obtained by integration the analytical solution of the field generated by a circular filamentary current placed between two linear and homogeneous semi-infinite media. It is considered that the windings are wound with a round wire. The model also gives the magnetic field...
