In a conventional power supply device for a xenon short arc lamp, a power transformer is connected to an AC power source, followed by a rectifier, a smoothing circuit, etc., and a current control circuit or a power control circuit, etc. are connected as necessary. Although it is said to have an additional configuration, it has been pointed out that this has the drawbacks of being large and heavy. For this reason, recently, ultra-compact and lightweight power supplies employing a switching regulator system have been developed.

A power supply that uses this switching regulator method is small and lightweight, making it extremely easy to transport. It is in a situation where it can be easily used even in places like Along with this, there is a strong demand for commercial power sources that can be used in common for both 100V and 200V systems.

On the other hand, a power supply device for a discharge lamp adopting the above-mentioned switching regulator system has a structure that limits inrush current, and has a rectifier circuit device that is small and lightweight (for example, see Utility Model Publication No. 38-2750). ), but in this rectifier circuit device, for example, 100V
Or, it is not possible to share two 200V power supplies. Furthermore, it has been found that the conventional circuit for limiting inrush current is inadequate when restarting a discharge lamp instantaneously.

That is, FIG. 1 is an explanatory diagram of a conventional rectifier circuit device that is small and lightweight and limits inrush current, where P is an AC power supply, S 1 is a power switch, RF is a bridge rectifier circuit, C 1 , C 2 is a capacitor that constitutes a smoothing circuit, and m and n are output terminals. Generally, since the capacitance of capacitors C 1 and C 2 is large, immediately after closing the power switch S 1 , the bridge rectifier circuit RF A large inrush current flows into capacitors C 1 and C 2 through the bridge rectifier circuit.
Easy to damage RF. Therefore, an inrush current limiting resistor R1 is inserted in the power supply line, and a parallel circuit of a relay RY and a capacitor C3 is connected between the power supply lines via a diode D and a resistor R2 , and the relay The relay contact ry of RY is connected in parallel with the inrush current limiting resistor R 1 , so that the magnitude of the inrush current when the power switch S 1 is turned on is limited by the inrush current limiting resistor R 1 , and then the capacitor When C3 is charged, the relay RY is activated to close the relay contact ry, thereby shorting the inrush current limiting resistor R1 .

In the rectifier circuit device as described above, the time from when the power switch S1 is turned on until the capacitor C3 is charged to a predetermined voltage and the relay RY is activated depends on the voltage of the AC power supply P. , when the voltages are different, it is not possible to time the relay contact RY to close appropriately, and as a result, sufficient inrush current limiting effect cannot be obtained, or conversely, the current may be limited for an excessively long period of time. I come to do it. Therefore, simply next to the AC power supply P, for example,
It is not possible to share two power sources by providing a transformer with switching terminals for 100V and 200V, and if this were done, the advantages of small size and light weight of the power supply device would be completely lost.

On the other hand, a voltage doubler rectifier circuit is known that is constructed by combining a diode bridge rectifier circuit, two capacitors, and a changeover switch and is capable of reducing the size and weight (for example, see Utility Model Application Publication No. 111625/1983). ),
According to this voltage doubler rectifier circuit, it is possible to configure a power supply device that can share two systems of power supplies with different voltages.

However, a new problem has been discovered when using this voltage doubler rectifier circuit. i.e. power switch S 1
Immediately after opening the discharge lamp and turning off the discharge lamp, capacitor C3 starts discharging and the capacitor C3 starts discharging.
When the voltage of C3 becomes less than the operating voltage of relay RY, the relay RY is deenergized and the relay contact ry is opened. But capacitor C3 discharges and relay RY
After opening the power switch S 1 , it takes a considerable amount of time for the voltage to drop below the operating voltage of It has been found that even if the power switch S1 is instantaneously closed, the relay contact ry is still closed and the inrush current limiting resistor R1 may not act at all.

In this invention, as shown in Figure 2, one power line from the AC power supply P is connected to a bridge rectifier circuit.
Connected to one input terminal a of the RF, this power line has a power switch S 1 and an inrush current limiting resistor R 1 .
At the same time, the other power supply line is connected to the movable contact of the changeover switch S2 which has the other input terminal b of the bridge rectifier circuit RF as one fixed contact a, and the two outputs of the bridge rectifier circuit RF are connected to the movable contact of the changeover switch S2. A series circuit of two capacitors C 1 and C 2 constituting a smoothing circuit is connected between terminals c and d, and the other fixed contact of the changeover switch S 2 is connected to the connection point of both capacitors C 1 and C 2 . Establish a b. Also, the output terminals c, d
There is a relay RY and a capacitor C 3 through a resistor R 2 between them.
A parallel circuit is connected to this capacitor C 3 , and a series circuit consisting of a resistor R 3 with a small resistance value and a switch S 3 is connected in parallel to this capacitor C 3 as a relay return circuit, and the relay contact ry of the relay RY is is connected in parallel with the inrush current limiting resistor R1 .

Since the present invention has the above-described configuration, when the changeover switch S2 is connected to the input terminal b of the bridge rectifier circuit RF, which is one of the fixed contacts A, as shown in the figure, the bridge circuit RF is completely switched off. It functions as a wave rectifier circuit, but the selector switch S 2
is switched to the other fixed contact RO, the two rectifying elements D 1 ,
D 2 and capacitors C 1 and C 2 constitute a full-wave voltage doubler rectifier circuit. Therefore, if the voltage of the AC power supply P is constant when the changeover switch S2 is turned on to the other fixed contact B, and when the changeover switch S2 is switched to the one fixed contact A,
A certain voltage V is applied between the output terminals m and n of this circuit, respectively.
Then, a DC output of half the voltage V/2 can be obtained. In other words, it means that it is possible to obtain the same DC output whether the AC power supply P is at a certain voltage or twice that voltage. It is possible to share the power supply.

Also, since the same voltage output is obtained between output terminals m and n in either case, relay RY operates with exactly the same time difference and closes relay contact ry in both cases. Because of this,
Inrush current limiting resistor R 1 allows power switch S 1
The inrush current when the circuit is closed can be restricted reliably and in a desired manner, and the power switch S1 , the bridge rectifier circuit RF, etc. can be sufficiently protected from damage.

Furthermore, in the present invention, a relay recovery circuit including a switch S 3 that operates in conjunction with the power switch S 1 is provided in parallel with the capacitor C 3 for operating the relay RY. When the switch S 3 is opened, the above-mentioned relay operation is not obstructed, and when the power switch S 1 is opened, the switch S 3 is closed at the same time, and the charge in the capacitor C 3 is instantly discharged. As a result, relay RY is deenergized and relay contact ry immediately returns to open state. Therefore, even if the power switch S 1 is opened and then closed again, the inrush current is reliably limited by the inrush current limiting resistor R 1 .
After all, the discharge lamp can be restarted freely without being subject to time constraints.
