Performance analysis of single film electrode of the L-C resonance capacitors for using high-frequency induction heating processing equipment

Abstract

Recently, a world is the point of need with new energy of high efficiency measures according to global climate change issues and energy shortages. [1] One of the various measures an energy control is to design and development at a precise circuit that can be used conservation and efficiency as the center with the power in industrial apparatus. High-frequency induction heat treatment industrial facilities are processing to the heating target by utilizing the changed resonant frequency AC power from the inverter. [2] [3] At this time, the core components are applied to behind inverter, which is an induction coil and film capacitor for high frequency resonance. In general, commercialization capacitor at domestic is developed by the focuses to the general-purpose components used in electronic circuit. [2] [4] [5] Especially, in this paper proposed high-frequency resonant capacitor does not consist of little research in the country. The Capacitors for LC resonance can be designed variety of possible according to capacitance, maximum power and allowable voltage. [8] And, high-frequency induction heat treatment, as well as a range of uses in many industries is expanding to excellent characteristics for high voltage and frequency. Therefore, it is time to secure the necessary skills to develop first, and require a comprehensive study to be produced domestically. Here, the change of volume and size at film according to the experimental results to determine electrode of capacitance, inductance, impedance and resistance. The process of comparing design theory and experimental results confirm error due to frequency change, and it offers the most ideal way to create a capacitor. The data item for measuring is such as Dimensions, Capacitance, Sinusoidal Voltage, Max Current and Frequency Limit. The maximum power 150kVar and frequency range 700kHz is the total capacity of target model to analyze.
