この発明はスイッチング電源全使用した横流形炭酸ガス
レーザ装置に係シ、特に電源部分の実装に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cross-flow type carbon dioxide laser device that uses a switching power supply entirely, and particularly to mounting of a power supply portion.
従来、横流形炭酸ガスレーザ装置は第１図に示すように

４は電源部至に接続されている。Conventionally, a cross-flow type carbon dioxide laser device is constructed as shown in FIG. A stabilizing resistor 4 is connected in series to each of the divided electrodes (cathode) 2. Therefore, the common electrode 1 and the stabilizing resistor 4 are connected to the power supply section.

４を介して放電部且に供給している。During operation, a three-phase 200V power source is rectified, smoothed, and converted into a direct current, and the voltage (current) is switched by the full-bridge connected MO8 type field effect transistor 6. Then, the high-frequency voltage is boosted by a step-up transformer 7, rectified by a rectifier bridge 8, smoothed slightly, and then supplied to the discharge section via a stabilizing resistor 4.

くなる。When trying to increase the carrier frequency of switching between power supply units and make the power supply unit 5 more compact and highly efficient, air-cooled MO
The heat loss of the 8-type field effect transistor 6 increases, and the temperature rise increases. To overcome this problem, it is necessary to blow a powerful wind to cool the device, but this can blow in dust and moisture from the surrounding area, which may reduce the reliability of the power supply parts. Furthermore, in order to overcome the above problem, the MO8 type field effect transistor 6 must be attached to a large heat sink, resulting in a disadvantage that the power supply section becomes large. In addition, when looking at the entire carbon dioxide gas radar device, the oil tanks are distributed in two or more locations (when the switching power supply is divided into two or more sets in a large device), which increases the price of the device.
