고주파 인버터를 이용한 고효율 오존발생기의 특성에 관한 연구
김영훈,노인배,우성훈,우정인 東亞大學校 2002 東亞論叢 Vol.39 No.-
Recently deep interests and attractions have been paid on the generation of ozone with environment polisy. Especially, which is widely used to remove bad smell and to clear water. This paper presents control and performance of a voltage source IGBT inverter developed for silent corona discharge type ozonizer. And proposed addition circuit for maintain discharge the center of in the airgap. In this paper, schemed equivalent electric circuit of the discharge eletrode for simulation. Finally, the effectiveness of this discharge tube character of ozonizer is investigated in the simulation and experimental results.

We proposed the speed control of the inverter-fed SLIM(Single-sided Linear Induction Motor) for conveyance system by the decoupled thrust control with DSP board. The voltage equations of SLIM are expressed on the suitable α-β axis by the proposed equivalent circuits, which can analyze the characteristics of the thrust and the normal force and so on. These control methods, which are the slip angular frequency control and the decoupling control for the thrust and normal force by analyzing these parameters can be successfully driven without interfering of each axis. These results exemplified the linear drive of SLIM with the reference value.

In this paper, we developed the multi-function vertical digital automatic welding carriage with the display type. Firstly, we construct current and voltage digital control system for welding condition decide using digital input switch and D/A converter circuit. The proposed system controller has high economics, small size and robust characteristic to noise. Because it using PIC16C74 microprocessor. Characteristic of PIC16C74 is RISC-Like type, low cost, high output current. And For the improvement of efficiency and out response of weaving motor and traveling motor, we design and control PWM inverter using Digital PID controller.
