“…Los interruptores resonantes de voltaje cero se presentan cuando el condensador C r se conecta en paralelo con el interruptor para obtener la conmutación por voltaje cero (ZVS), puede operar en modo de media onda o de onda completa [24]. Wang et al [13] estudiaron un inversor cuasi-resonante serie con regulación de potencia de salida variable con frecuencia fija y múltiples salidas (múltiples quemadores), conmutación por ZVS y control de PWM.

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.

Abstract-An exhaustive method for verifying & optimizing of switching frequency for the performance of high frequency mirror inverter for induction heater is presented. Litz-wire is used for heating coil of the induction heater which controls the skin effect and proximity effect of conductor operating at high frequency. With the calculated optimum values of inductance and resistance at a particular operating frequency, HF mirror inverter topology has been simulated using P-SIM. Optimum results are obtained by changing the switching frequency. Obtained results are then compared using different power semi-conductor switches like IGBT, BJT, MOSFET and GTO. Afterwards waveforms have been shown & we can see that at a particular switching frequency output is highly quality & can justify the feasibility for real implementation of high frequency mirror inverter fed induction heater in industrial appliancesIndex Terms-Induction heating, mirror inverter, P-SIM, semi-conductor switches, ZCS and ZVS I. INTRODUCTIONInduction heater for industrial applications operates at a high frequency range from 1 kHz to 100 kHz [1]. Here switching frequency varies between 20 kHz to 40 kHz. In the application of low frequency induction heating, the temperature distribution can be controlled by slowly varying magnetic fields below a frequency as low as 300 Hz. For medium frequency application, an auxiliary voltage-fed inverter is operated in parallel with the main current-fed inverter since the current-fed parallel inverters alone, when used for induction heating, fail to start. Mirror inverters [2], [3] for high frequency induction heating and melting applications are self-started. For self-commutation, a resonant circuit is essential. It is assumed that the circuit is under damped; a mandatory condition for the circuit. The capacitor required for under damping can be connected in series or in parallel with the load. In the modern times, IGBTs, MOSFETs, GTOs are preferred to SCRs mainly because they offer convenient turn OFF Computer and Electrical Engineering, Vol.4, No.1, February 2012 14 II. ANALYSIS OF HIGH FREQUENCY MIRROR INVERTERIn the circuit operation has been discussed in detail. The exact circuit diagram of the mirror inverter [16] is shown in Fig. 1. As soon as gate pulse is applied to IGBT-1, C1 gets discharged through 'QLMN' loop & C2 gets charged 'QLMNC' path. In the next cycle when input signal is given to IGBT-2 with gate pulse to IGBT-1 is removed, C2 gets discharged through 'NMDC' loop & C1 gets charged through 'QNMDC' path. Thus a frequency current flows through 'MN' bar in alternate direction & due to the low capacitive reactance of the capacitor 'C', this current also flows through the coil inductor. In this way, radio-frequency current generated in the short-circuited bar 'MN' is reflected into the induction coil. Now this current will generate alternating magnetic flux.A & B points in the above mentioned circuit .At first when we connect the converter circuit with the D.C power supply of the system the capacit...

“…[3] has discussed all this parameters extensively for different applications. Regarding power converters for domestic heating applications, voltage source converters are commonly used instead of current source converter; among these converters single switch, half bridge and full bridge configurations are the main choices depending on the power range [4][5][6][7][8][9]. Several ac -ac topologies have been proposed to simplify converter and improve the efficiency [10]- [16] even for domestic induction heating [13].…”

this paper presents the analysis and design of a new high frequency ac-ac converter applied to domestic induction heating. The proposed topology uses only four switches to control power. Converter operation is same as a conventional class D inverter. Working above the resonant frequency, a sinusoidal input current and a unit power factor are obtained. To bring higher efficiency and power density, application of emerging SiC technology in proposed converter has been evaluated. The analytical and simulation results have been verified by means of a 380-W induction heating prototype.
