Abstract

PURPOSE:To enhance the efficiency by decreasing a large ripple voltage generated upon stabilizing of an input current due to the operation of a choke by a circuit which utilizes a capacitor and a diode, thereby reducing the power loss due to the resistance. CONSTITUTION:A current flowed from a DC power source 1 to a choke 2 is supplied through a starting auxiliary resistor 3 to the bases of transistors 4, 5, which are conducted. Thus, ultrafine resonance of the inductance content of a transformer 6 and a capacitor 7 starts, and two transistor 4, 5 are alternately conducted and oscillated. A capacitor 11 is charged through a diode 10 or 11 at this time, and charge stored in the capacitor 11 is supplied through resistors 13, 14 to the bases of the transistors 4, 5.

ース電流をトランジスタ４及び５に供給できる。Hereinafter, one embodiment of the present invention will be explained first. A current from the DC power source 1 passing through the choke 2 passes through the starting auxiliary resistor 3, and a base current is supplied to the bases of the transistors 4 and 5, making the two transistors conductive. Therefore, current flows through the windings 6-1, 6-2 of the oscillation transformer 6, and a minute resonance begins between the inductance and the capacitor 7 of the oscillation transformer 6, and the minute voltage is applied to the base winding 8. This causes a difference in the base voltages of the two transistors 4 and 5, making one conductive and the other non-conductive. Due to resonance with the inductance of the oscillation transformer 6,
The two transistors alternately conduct and oscillate. At this time, a ripple voltage is generated due to the current stabilizing effect of the choke, and the voltage shown in FIG. 2 is applied to the capacitor 9, and the voltage shown in FIG.
The current shown in the figure flows. The current on the + side in FIG. 6 charges the capacitor 11 through the diode 10, and the current on the O side in FIG. 3 flows through the diode 12. The charge stored in capacitor 11 is supplied to the bases of transistors 4 and 5 through resistors 16 and 14. Therefore, the voltage of the capacitor 11 can be set to a lower value than the power supply voltage, and another embodiment is shown in FIG. 4 in which the power loss of the resistors 15 and 14 can be reduced. According to FIG. 4, when the voltage of the capacitor 11 becomes equal to or higher than the Zener voltage of the Zener diode 15, the base current is supplied to the transistor 16 through the Zener diode 15, so the collector current of the transistor 161C flows, and the capacitor 9 and the diode 10 A portion of the current flowing through the transistor 16
Since it flows through the capacitor 11, the voltage of the capacitor 11 is
The voltage is stabilized at a voltage determined by the Zener voltage of the Zener diode 15. Therefore, a constant base current can be supplied to transistors 4 and 5 regardless of fluctuations in power supply voltage.

ある。FIG. 5 shows that the aforementioned power supply device includes a DC power supply 1 and a choke 2.
In contrast, the AC power supply 17 is configured with a full-wave rectifier 18.
A power supply device configured to rectify the current through the power source and smooth it with a capacitor 19 is used. According to such a configuration, the ripple voltage generated in the capacitor 19 is accumulated in the capacitor 11 through the capacitor 9 and the diode 10,
Transistor 200 base power can be obtained. Using this capacitor 11 as a power source, a control circuit formed by an IC oscillation circuit or the like is operated to obtain an on/off signal for the transistor 2°, and an intermittent current is caused to flow through the transformer 21 to cause it to oscillate. Note that operation is possible even without the capacitor 19. FIG. 6 shows an example in which a push-pull type inverter circuit is used, using a power supply device that rectifies an AC power supply 17 through a full-wave rectifier 18 and smoothes it with a capacitor 19.
