PURPOSE:To suppress surge voltage and reduce a loss from a power source and thus obtain a miniaturized power source for a laser efficiently, by providing secondary windings for a stabilization reactor and regenerating energy stored in the stabilization reactor toward the preceding stage of a voltage control circuit which is arranged at the input side of the stabilization reactor. CONSTITUTION:This device allows secondary windings of a stabilization reactor 14A to be clamped by voltage at both ends of a smoothing capacitor 4 and voltage which is determined only by a turn ratio is impressed at the primary side. The proper application of the turn ratio makes it possible to suppress voltage produced at the primary side of the stabilization reactor 14A to a level that is less than constant voltage. Similarly, even when FETs 9B and 9C for switching is turned to ON, the same operations are repeated. Further, even when the FET 9B and 9C for opposite phase switching is turned to ON before the regeneration of the stabilization reactor 14A is completed, its regeneration is kept on and there is no effect on the opposite phase. |
