Abstract
In this paper is give a procedure for calculating the parameters of series resonant circuit for converter that operates in the mode of induction heating device. Designing the power converter in the general caseis is complex process. The process on design of the power converter is defined with the purpose of the converter, and output load. Output load of converter defines the required output power, output voltage, output current, output frequency. From the physical state of the output load on the converter depends configuration of hardware and software part of control electronics. The work is simple if the output load is a stationary, timeable not changed, such as output load in the mode of motor or regulated source of voltage. But the design of converter is complicated if the physical state of the output load is a dynamic, time-variable process and its dynamic affects on output variables of the converter: impedance, voltage, current, power, frequency. Such output load has in power converter burdened with serial resonant circuit in the mode of induction device. The mode of induction heating changes the impedance of resonant circuit and it affects on the voltage, current and power on the converter. So the design on the converter with such load, requires knowledge of the dynamics of the process. In general case, determining the dynamics of the process on the induction heating requires solving Maxwell's equations for given geometry, medium and conditions. It makes the process of design of power converter with output load in the mode of induction device complex. Thus design of the converter for such loads for engineers is complex and hard process that requires knowledge not only of power electronics but also and from electrothermals process.
Determining on the parameters of the resonant circuit for converter in mode on device for induction heating can be done by calculations and simulations. With simulation programs are getting a quick solution for the dynamic on the parameters of the resonant circuit. But accuracy depends from the particular program, i.e. from the numerical methods that are based program. Best is before use simulation programs, the parameters of the resonant circuit to be determined through calculations. In this paper for converter that operates in the mode of induction heating device is give a procedure for calculating the parameters of resonant circuit. The calculate are the switching frequency, the power, current, inductance and resistance for converter with output resonant circuit.
