れる。FIG. 4 shows an embodiment of the present invention, in which one terminal p of the AC power supply 11 is connected to the on-side terminal of the operation switch 12, to the transistor Tr, to the capacitor C, and to the relay coil 13 via the diode D1. is connected to the other terminal q of the AC power supply 11, the pace of the transistor Tr is connected to the terminal qKM' of the AC power supply 11 via the capacitor C2, and both ends of the capacitor C2 are connected to the other terminal q of the AC power supply 11. A closed circuit is formed through the secondary winding of the transformer 14, and one end of the primary winding of the transformer 14 is connected to the connection point between the on-side terminal 12b of the operation switch 12 and the diode D, and the other end is connected to terminal q of AC power supply 11. Also, the connection point between the emitter of the transistor Tr and the capacitor CI is

12c is connected to terminal q of the AC power source via a resistor R.
ナオトランス14は移相反転用のトランスである。The NAO transformer 14 is a transformer for phase shift conversion.
次に本発明の動作について説明する。Next, the operation of the present invention will be explained.
交流電源11の電圧波形において端子pがプラス、qが
マイナスの状態について考えると、電流は、p→12a
→12’b→D1→Tr のコレクタでトランジスタ
Trはオフ状態の為、電流は流れない。Considering a state where terminal p is positive and terminal q is negative in the voltage waveform of AC power supply 11, the current changes from p→12a
→12'b→D1→Tr Since the transistor Tr is in the off state at the collector, no current flows.
次にp→12a→12b→トランス14の1次側→qと
流れる。トランスの1次側において、実線矢印方向に電
流が流れるが、このトランスit−位相反転用トランス
であるので、トランスの2次側においては、実線矢印方
向に電流が流れようとするが、ダイオードD、のため電
流は流れない。Next, it flows as p → 12a → 12b → primary side of transformer 14 → q. On the primary side of the transformer, current flows in the direction of the solid line arrow, but since this transformer is a phase inversion transformer, on the secondary side of the transformer, current flows in the direction of the solid line arrow, but the diode D , so no current flows.
次に交流電源の極性が逆になって側端子が+。Next, the polarity of the AC power supply is reversed and the side terminal becomes +.
p端子が−となると、トランス14の1次側KIri矢

2次側には実線矢印方向と反対方向すなわち破線で示し
た方向に電流が流れ、コンデンサC2は図示の極性に充
電されるので、トランジスタTrは導通可能の状態にな
る。When the p terminal becomes -, a current flows in the direction opposite to the arrow on the primary side of the transformer 14, and as a result, a current flows on the secondary side of the transformer in the direction opposite to the direction of the solid arrow, that is, the direction shown by the broken line. Since the capacitor C2 is charged to the polarity shown, the transistor Tr becomes conductive.
次に交流電源の極性が再び変化して、p端子がt、側端
子か−となると、トランジスタTrはオン状態となるの
で、電流は
a−+ l 2a−+ l 2cm+ D、 −+ T
r−* Q、 −+ l 3−+ bと流れて、リレー
は作動する。Next, when the polarity of the AC power source changes again and the p terminal becomes t and the side terminal becomes -, the transistor Tr is turned on, so the current is a-+ l 2a-+ l 2cm+ D, -+ T
The flow is r-*Q, -+ l 3-+ b, and the relay is activated.
操作スイッチSWをオフ側に切り換えると、コンデンサ
CIの電流は
C1→D2→12d→12cm+R→13を通って流れ
るので、リレーは復帰する。When the operation switch SW is turned off, the current in the capacitor CI flows through C1→D2→12d→12cm+R→13, so the relay returns to its original state.

帰する。When the operation switch is turned on as described above, the circuit of the present invention starts operating at the zero point of the second half wave, as shown in FIG. 5, regardless of the input phase. Also, when the operation switch is turned off, the relay returns to normal operation due to the discharge current of the capacitor, similar to the conventional circuit.
