This paper investigates the solid state transformer applied for the HVDC transmission from the offshore windfarm. The 5kVA experimental setup is developed and comparison of 50Hz, 400Hz and 1000Hz operation. Dependency of the loss in the transformer with different core materials to frequency is investigated. Frequency loss dependency of several core materials are compared with experimental measurement...
This paper shows the research on wireless power transfer of a mixing system. The mixer can mix and heat middle and high viscosity solutions by using induction heating of mixing blade. The power can be supplied from the top of the container by the wireless power transmission coil. The energy balance is shown from the heat loss and the heating power of the components obtained by the experiments and...
We have conducted study on wireless power transfer to mixing system, which can mix and heat simultaneously medium or high viscosity solution with mixing blade heated by induction heating. This system needs to supply an electric power from the top of the metal container, because it consists of a vertical type mixing blade and an IH coil for induction heating, a metal container, a low voltage high frequency...
In this paper, the fast heating up impeller and container directly by induction heating is proposed. Simultaneous heating of the impeller and the container leads to the homogeneous and rapid heating for the chemical reaction. To show the feasibility of proposed method, the induction heating of the double layer of the stainless steel plates are investigated. Experimental results show the good feasibility...
In this paper, the feasibility of the simultaneous induction heating of the impeller and the vessel of the mixer. For basic investigation, the experiments of the double plates configuration is investigated. New equivalent coil measurement method is also shown. By using this method, the equivalent circuit of the induction heating system can be also easily estimated. The experimental results show the...
In the chemical industry, the mixer or agitator is widely used. To mix the liquid of high viscosity and promote the chemical reaction, heating up the liquid till the proper temperature for the reaction is popular method. Usually the heater is set at outside of the outer vessel. Then getting homogeneous temperature inside the liquid takes long time. The longer the inhomogeneous time is, the larger...
