本発明回路例第１図について以下に説明する。The circuit example of the present invention shown in FIG. 1 will be explained below.
コンデンサ３の端子電圧は、電源１より負荷１１とダイ
オード２を通して、半波整流されている。The terminal voltage of the capacitor 3 is half-wave rectified from the power supply 1 through the load 11 and the diode 2.
抵抗器５の端子電圧１３法 コンデンキ３の端子電圧を
抵抗器４によって分圧されているため、電源１の周期に
同期したリップルを含む直流電圧である。Method 13: Terminal voltage of resistor 5 Since the terminal voltage of the condenser 3 is divided by the resistor 4, it is a DC voltage that includes ripples synchronized with the cycle of the power supply 1.
一方、コンデンサー８の端子電圧１４は、コンデンサー
３の端子電圧より、抵抗器７を通して充電されている。On the other hand, the terminal voltage 14 of the capacitor 8 is charged through the resistor 7 from the terminal voltage of the capacitor 3.

性サイリスタ９のゲート端子に流れる。After a certain predetermined period of time, when the terminal voltage 14 of the capacitor 8 reaches the terminal voltage 13 of the resistor 5, the thyristor 6 connected thereto operates, and the electric charge charged in the capacitor 8 is transferred to the resistor 10. It flows through thyristor 6 to the gate terminal of bidirectional thyristor 9.

ているため、コンデンサ−８の端子電圧１４が抵抗器５
の端子電圧１３に達するときは、かならず、電源１の電
圧がゼロ値附近である。At this time, since the terminal voltage 13 of the resistor 5 includes a ripple, the terminal voltage 14 of the capacitor 8 changes to the terminal voltage 13 of the resistor 5.
When the terminal voltage 13 of is reached, the voltage of the power supply 1 is always close to the zero value.

ンデンサー８と抵抗器１０の値を設定すれば、双方向性
サイリスタ９は電源１の電圧のゼロ値でオン状態になり
１サイクル以上（希望の・値に設定できる。□ Then, if the values of the capacitor 8 and resistor 10 are set so that the current continues to flow to the gate terminal of the bidirectional thyristor 9 for more than half a cycle of the period of the power supply 1, the bidirectional thyristor 9 will be able to maintain the voltage of the power supply 1. It turns on at zero value and lasts for one cycle or more (can be set to desired value).
）オン状態を保持して、電源１の電圧のゼロ値でオフ状
態になる。) It maintains the on state and turns off when the voltage of the power supply 1 reaches zero value.
オフ状態の時間は、抵抗器１の値で希望の値に設定でき
る。The off-state time can be set to a desired value by the value of resistor 1.
以上のように本発明回路は、複雑な回路を構成せず少な

取除くことができ、さらに可動部分がないので、寿命を
半永久にした。As described above, the circuit of the present invention can eliminate radio wave interference noise caused by switching without configuring a complicated circuit and with a small number of circuit parts, and furthermore, since there are no moving parts, the circuit has a semi-permanent life.
本発明の実施例として、
従来交流電動機の回転数制御を電圧によって制御してい
たが、電圧を下げると回転トルクが低下するため、低速
回転数にするためあまり電圧を下げると、交流電動機が
起動しなくなってしまった。As an embodiment of the present invention, the rotational speed of an AC motor has conventionally been controlled by voltage, but if the voltage is lowered, the rotational torque will decrease, so if the voltage is lowered too much to achieve a low rotational speed, the AC motor will not start. I no longer do it.
これを、本発明回路を使用すれば、交流電動機には間欠
的に全電圧が加えられるため、起動トルクが低下するこ
とがなく、見掛回転数を超低速回転数まで下げることが
可能になった。However, if the circuit of the present invention is used, full voltage is intermittently applied to the AC motor, so the starting torque does not decrease and the apparent rotational speed can be reduced to an ultra-low rotational speed. Ta.
