【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、波形制御装置、特に最大値を維持しながら
実効値を低下させる波形制御装置に関するものである。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waveform control device, and more particularly to a waveform control device that reduces an effective value while maintaining a maximum value.
電力需要家において、その電力需要量（電力消費量）
を抑制して電力料金の低減を図ることは経済的な面から
切実な問題である。Power demand (power consumption) at power consumers
It is a serious problem from an economical point of view to reduce the power rate by suppressing the power consumption.
電力需要量を抑制するには受電点の電圧の実効値を低
下させることによって、その目的をはたすことができ
る。しかしながら、蛍光灯や、水銀灯等の放電灯、また
はマグネットスイッチ等のように、或る値以下に電圧が
低下すると、その機能がはたせなくなる電気機器があ
る。したがって、単に電圧の実効値を低下するだけで
は、或る電気機器について動作しなくなる可能性がある
ので実用的ではない。In order to suppress the power demand, the purpose can be achieved by lowering the effective value of the voltage at the power receiving point. However, there is an electric device such as a fluorescent lamp, a discharge lamp such as a mercury lamp, a magnet switch, or the like, which loses its function when the voltage drops below a certain value. Therefore, merely lowering the effective value of the voltage is not practical because there is a possibility that an electric device may not operate.
本発明の目的は、最大値を維持しながら実効値を低下
させる波形制御装置を提供するとにある。An object of the present invention is to provide a waveform control device that reduces the effective value while maintaining the maximum value.

整することを特徴としている。[Means for Solving the Problems] The waveform control device of the present invention includes a center leg, a shell-type transformer core having a yoke portion having a cross section smaller than that of the center leg, and wound around the center leg, A primary winding with a tap to which a sine wave AC voltage is input; and a secondary winding with a tap which is wound around the yoke and outputs a voltage whose waveform is controlled, wherein the primary winding is provided. The width of the base of the peak wave of the output voltage waveform is adjusted by switching the taps, and the maximum value of the output voltage waveform is adjusted by switching the taps of the secondary winding.
第１図は、本発明の波形制御装置の基本回路図であ
る。この波形制御装置は、外鉄型変圧器鉄心１を備え、
この鉄心の中央脚にはタップ付き１次巻線２が巻かれて
いる。また、継鉄部は中央脚よりも断面が小さくなるよ
うに構成されており、継鉄部にはタップ付き２次巻線３
が巻かれている。FIG. 1 is a basic circuit diagram of a waveform control device according to the present invention. This waveform control device includes a shell-type transformer core 1,
A tapped primary winding 2 is wound around the center leg of the iron core. In addition, the yoke portion is configured to have a cross section smaller than that of the center leg, and the yoke portion has a secondary winding 3 with a tap.
Is wound.
１次巻線２のタップ４は起磁力（アンペア・ターン）
を変えるためのものであり、２次巻線のタップ５は出力
電圧の最大値を調整するためのものである。Tap 4 of primary winding 2 is magnetomotive force (ampere turn)
, And the tap 5 of the secondary winding is for adjusting the maximum value of the output voltage.
次に、本実施例の動作を、第２図の波形図を参照しな
がら説明する。Next, the operation of this embodiment will be described with reference to the waveform diagram of FIG.
波形制御装置の入力端子7a,7bに電源電圧である正弦
波交流電圧E1が印加されると、１次巻線２に電流が流
れ、この電流の値を巻数との積（アンペア・ターン）で
定まる起磁力により位相が90゜遅れた磁束Φ１が発生さ
れる。この磁束Φ１は、中央脚を通り、２つの継鉄部で
磁束Φ２に分かれる。磁束Φ１は正弦波であるが、磁束
Φ２は或る磁束密度以上では急に飽和して一定値とな
り、ｄΦ2/dt＝０、従って２次起電力は０になる。すな
わち継鉄部が未飽和の期間だけ磁束Φ２が変化し、その
結果２次起電力E2はピーク波となる。電圧E2は２次巻線
の出力端子8a,8bから出力される。When the input terminal 7a of the waveform controller, sine wave AC voltage E 1 is the power supply voltage 7b is applied, a current flows through the primary winding 2, the product of the number of turns the value of the current (ampere-turn) magnetic flux [Phi 1 delayed in phase by 90 ° are generated by the magnetomotive force determined by. This magnetic flux Φ 1 passes through the central leg and is split into magnetic flux Φ 2 at two yoke portions. The magnetic flux Φ 1 is a sine wave, but the magnetic flux Φ 2 suddenly saturates and becomes a constant value above a certain magnetic flux density, and dΦ 2 / dt = 0, and therefore the secondary electromotive force becomes zero. That only the magnetic flux [Phi 2 is changed period of the yoke portion is unsaturated, result 2 TsugiOkoshi power E 2 is the peak wave. Voltage E 2 is the output terminal 8a of the secondary winding, output from 8b.
以上のことから、継鉄部の未飽和の期間を変化させれ
ば、出力電圧E2の波形のピーク波の基底部（なお、基底
部とはピーク波の０ボルトレベル部分である）の幅ｌを
制御できることがわかる。すなわち、タップ４を切換え
てアンペア・ターンを大きくすると磁束Φ２が大きくな
る結果、継鉄部の未飽和の期間が小さくなり、出力電圧
E2の波形のピーク波の基底部の幅ｌは小さくなる。逆
に、アンペア・ターンが小さくなるようにタップ４を切
換えると、磁束Φ２が小さくなる結果、継鉄部の未飽和
の期間が大きくなり、出力電圧E2の波形のピーク波の基
底部の幅ｌは大きくなる。From the above, by changing the duration of the non-saturation of the yoke portion, the width of the base of the peak wave of the output voltage E 2 of the waveform (Note that the base portion is a 0 volt level portion of the peak wave) It can be seen that 1 can be controlled. That is, by increasing the ampere-turn by switching the tap 4 results flux [Phi 2 becomes larger, the smaller the period of non-saturation of the yoke portion, the output voltage
Width l of the base of the peak wave E 2 of the waveform is reduced. Conversely, if the tap 4 is switched so that the ampere-turn becomes smaller, the magnetic flux Φ 2 becomes smaller, so that the non-saturation period of the yoke becomes larger, and the base of the peak wave of the waveform of the output voltage E 2 becomes The width l increases.
一方、出力電圧E2の最大値Emを、入力である正弦波交
流電圧E1に等しくなるようにするためには、２次巻線の
タップ５を切換える。すなわち、巻数が大きくなるよう
にタップを切換えると最大値Emは大きくなり、逆に巻数
が小さくなるようにタップを切換えると最大値Emは小さ
くなる。On the other hand, the maximum value E m of the output voltage E 2, in order to be equal to the sinusoidal alternating voltage E 1 is input, switches the tap 5 of the secondary winding. That is, the number of turns is a maximum value E m is increased when switching the tap to be greater, the maximum value E m when switching the tap to the number of turns in the opposite smaller decreases.
したがって、１次巻線２のタップ４および２次巻線３
のタップ５の切換えを調整することによって、最大値を
維持しながら実効値を低下させることが可能となる。Therefore, tap 4 of primary winding 2 and secondary winding 3
By adjusting the switching of the tap 5, the effective value can be reduced while maintaining the maximum value.
したがって、このように制御された波形の電圧によ
り、蛍光灯や、水銀灯等の放電灯、またはマグネットス
イッチ等のように、或る値以上の電圧を必要とする機器
の機能を保持しながら、電力消費量の低減を図ることが
可能となる。Therefore, the voltage of the waveform controlled in this manner allows the power of a device requiring a voltage of a certain value or more, such as a fluorescent lamp, a discharge lamp such as a mercury lamp, or a magnet switch, to be used while maintaining the power. It is possible to reduce consumption.
