The research of stabilization properties of inductive-capacitive converters based on the two-sections hybrid electromagnetic elements

Abstract

Inductive-capacitive converters (ICC) are used in power current stabilization systems (CSS). These include charge capacitive storage device (CCSD), high voltage pulse generators, electrothermal systems, and gas-discharge lamps. They require constant power if their resistance is changed in the wide range. The authors proposed to supply the load with the help of ICC based on hybrid electromagnetic elements (EME). Multifunctional integrated electromagnetic components (MIEC) belongs to them. The application of MIEC in ICC can improve the efficiency and reduce the weight and dimensions of CSS. The elements of ICC are selected according to the accuracy of the load current stabilization. This requires the calculation of electromagnetic processes in ICC. The authors developed the mathematical model of ICC based on the two-section MIEC. This model evaluates the stabilization properties and frequency responses of ICC in CSS. The authors developed the model for the research of electromagnetic processes. The model is built with the integral parameters of MIEC. They include full inductance of the electrical electrodes, the total capacity and the current of the electrical leads. As a result, it was confirmed that a change in the voltage amplitude of MIEC can regulate the level of constant current in the load when MIEC is powered with the inverter. The load current at the resonant mode of MIEC is directly proportional to the supply voltage consequently. We can use these MIEC schemes in charge process of storage capacitor (SC). Thus, linearly increasing voltage is obtained. In it turn, it helps to make charge process of SC economical and energy efficient. Application of MIEC in CCSD reduces weight and dimensions of the device. Two-sections MIEC with successively-connected sections and diagonal connection of the power supply and the load with the electrical lead in the middle of the secondary electrode is expedient to use in devices whose transfer functions should be close to unity, such as in ICC.
