る。[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a rectifier circuit, a smoothing capacitor having a DC output end, and a winding and an iron core disposed on at least one power supply conductor side of the rectifier circuit. A low-pass filter for a power consumer, comprising: a chiyoke coil having a wire, and an end of the chiyoke coil opposite to the one power supply conductor side is connected to the other power supply conductor side of a rectifier circuit via a capacitor. .

Known rectifier circuits with smoothing capacitors include:
The drawback is that it has a significant retroactive effect on the power supply network. When this rectifier circuit is connected to a power source, the capacitor is charged. This capacitor is designed with a fairly large capacitance in order to keep the output voltage as constant as possible. If a power consumer is connected, abnormal peaks occur in the primary current waveform that must be filtered out. This is because the harmonics caused by the peaks disturb the power network, especially when high-frequency control pulses are sent through this power network, as is common at current power supply frequencies (e.g. audio frequency control device).

荷時に大きな電圧上昇を与える。 In order to eliminate the above-mentioned difficulties, iron cored chiyoke coils are introduced into the rectifier circuit, and in some cases they are arranged symmetrically. These choke coils must be designed to provide extremely strong action. Furthermore, capacitors are also used.
The above-mentioned series circuit of the iron-core chiyoke coil and the capacitor forms a series resonant circuit, and this circuit gives a large voltage rise when there is no load.

とする。 Electronic filters have also already been developed to low-pass or control the retroactive effect of the above-mentioned circuits on the power supply network. In that case, semiconductor switching elements are used which regularly operate the power supply, and a load-independent DC voltage is obtained which is stabilized to a certain extent by the auxiliary arrangement of inductive loads and capacitors. The above circuit operates with high frequency pulses, which have a retroactive effect on the power supply and therefore require additional expensive filters.

つてのみ克服できる。 Even if the above-mentioned known measures make it possible to maintain a constant DC voltage and ensure that only extremely small harmonic components reach the power supply, and even if this circuit solves control and regulation problems, it results in extremely high equipment costs. The drawback is that this expense can only be overcome by making significant sacrifices.

A rectifier circuit is connected between these divided windings, and the iron core of the chiyoke coil has at least one magnetic shunt magnetic path that intersects with the axis of the divided windings. Therefore, harmonic components higher than the resonance frequency can be strongly attenuated. For particularly strong attenuation of disturbance frequencies of high frequencies, in particular of frequencies considerably higher than the resonant frequency, for example in the radio frequency range, each of the two power supply conductors of the rectifier circuit is provided with an intermediate tap.
Alternatively, this can be achieved by providing one chiyoke coil having two divided windings.

Furthermore, in order to form the device symmetrically, at least one winding of the chiyoke coil has two divided windings in series, and the iron core has a magnetic shunt path that intersects the axis of the divided windings. . In order to obtain an extremely high filter effect for one frequency or multiple frequencies, the rectifier circuit consists of a plurality of chain coils connected in series in a cascade, each having tap or split windings and a capacitor at the output end. .
