Abstract: PURPOSE: A metal body detection method is provided to prevent mis-detection of the metal body mixed in powder and to improve detecting performance. CONSTITUTION: Signals input from a detecting coil for metal body detection are detected at a specific interval for specific hours by a CPU(central processing unit). An algorithm for generating a detecting signal simply when the signal over a predetermined level is input is set up. Herein, the electronic noise transmitted via a coil is removed, and the mis-operation during detection is avoided. Thereby, the metal body detection method is easily applied to a place of defective surrounding or where high frequency is generated. According to the prevention of mis-operation due to the position and the shape of the metal body in the powder, stable working is possible.

Abstract: PURPOSE: A regenerative rectifier using an inverter is provided to reduce the cost while enhancing the energy efficiency and the function by using a minimum number of thyristor switching devices. CONSTITUTION: Six thyristor switching devices(S1-S6) supply a DC power converted from an AC power to a load(M). The first inductor(L1) gradually increases a current supplied to the load. When an energy is regenerated in the load(M), if a transistor switching device(Tr) is turned on, the regenerated energy is temporarily stored in the second inductor(L2). A diode(D) prevents a short between the load(M) and the switching devices(S1-S6) during the regenerating process. After all of the regenerated energy is stored in the second inductor(L2), when a thyristor switching device(Th) is turned on while the transistor switching device(Tr) is turned on, the temporarily stored energy is regenerated and supplied to an input AC power source.
