Abstract

PURPOSE:To realize operation of polarized magnet with an AC by controlling a control electrode of a semiconductor switching element connected in series with a coil with a voltage sent from a circuit consisting of a diode, a capacitor and a resistor. CONSTITUTION:When an AC voltage is applied across terminals (a) and (c), a current flows through a diode D capacitor C resistor R2 since resistors R1, R2 are set as R1>>R2. Moreover, when a gate voltage of SCR exceeds the predetermined voltage, the SCR turns ON. Thereby, a current of positive half cycle flows into a coil L1 in the set side. Meanwhile, when voltage and current are inverted, a current does not flow into the coil L1 and a charging voltage of capacitor C is gradually discharged. When the power supply voltage becomes positive again, a capacitor C is charged again. When a voltage of capacitor C increases gradually, a gate voltage of SCR drops and the SCR turns OFF and thereby the coil L1 becomes non-conductive. For the set operation, a voltage must be applied to the terminals (b) and (c). In this case, the same operation as described above is also carried out.

'&, current flows through diode D → capacitor C-1jR2cv resistor Rtk. and control terminal '5r: a control terminal in front of the semiconductor switching element M, for example, the gate r of the thyristor SCH.
When the applied gate voltage reaches about 0.7V, the thyristor SCR turns on (see Figure 2 (b) and (c)). Therefore, at this point, the coil L is filled with the current of the first positive middle cycle. On the other hand, when the power supply voltage is reversed and the polarity is reversed, the thyristor SCR passes current only in the positive direction, so the coil L at this point.

As the voltage of the circuit board 7'C gradually increases, the current flowing through the diode Dk passes through the resistor R, and the current flowing through the resistor Rtk becomes smaller (thus, the gate voltage becomes low), keeping the thyristor SCR on. The voltage applied to the gate is divided by the resistors R1 and 'R3 and becomes smaller, so the gate voltage is low). Even if the polarity becomes negative and then becomes positive again, in this case KH
Since the TIRERIS SCR is off, the coil L is not energized.
