“…Algunos casos especiales como el control de la zona de inducción y el control asimétrico de tensión son abordados en [29], [62]. El control por temperatura adoptado en [63] demuestra que las estrategias sencillas pueden resultar en alta eficiencia y alto factor de inducción con bajos costos y con topologías comunes como el inversor ZVS de un interruptor.…”

Este trabajo presenta la revisión de la literatura que relaciona los desarrollos de los sistemas de calentamiento por inducción. Inicialmente, se presenta una contextualización de la forma general de funcionamiento y se concentra en las características particulares para uso doméstico y de manera más específica en la electrónica de potencia. Se presentan los principios de operación, las topologías de inversores resonantes más usadas (serie, paralelo, híbrida, cuasi-resonante y de un solo interruptor), las estrategias de modulación, estrategias de control usando modulación de frecuencia, por ancho de pulso y por densidad de pulso y las metodologías de conmutación (suave y forzada). Finalmente, se hace un pequeño análisis sobre las áreas donde aún es necesaria la investigación tales como sistemas de calefacción por inducción con múltiples salidas, topologías de inversores de un solo interruptor y los inversores cuasi-resonantes.

“…Tn certain industrial applications, a homogeneous thermal distribution is also necessary to avoid problems in the workpiece caused by irregular thermal expansion. This problem, which is similar to the one considered in this paper, is analyzed in [7] and [8]. There, the authors propose an optimal inductor design method [7], and an estimating method of the power inverters control to obtain a homogeneous heat distribution [8].…”

In this paper, we study different solutions of flexible cooking zones for induction hobs. Particularly, we focus on the usage of mobile inductors in two dimensions. The main contribution is the development of a mobile induction system which allows to heat circular pots with any size, in any position, with a homogeneous heat distribution. The good performance of this solution is tested experimentally. We present a theoretical model of the induction heating process which we use to analyze the heat distribution in a pot, and the main parameters of the problem. We also evaluate different heating strategies with a prototype with one double mobile inductor. From the obtained results, we can establish the best activation strategy of the inductor rings and the motion strategy as a function of the size of the heated pot.

This paper presents a mathematical model of a power controller for a high-frequency induction heating system based on a modified half-bridge series resonant inverter. The output real power is precise over the heating coil, and this real power is processed as a feedback signal that contends a closed-loop topology with a proportional-integral-derivative controller. This technique enables both control of the closed-loop power and determination of the stability of the high-frequency inverter. Unlike the topologies of existing power controllers, the proposed topology enables direct control of the real power of the high-frequency inverter.
