Abstract
PURPOSE: To prevent a switching element from damaging and stably operate the element in a power supply circuit by independently forming two smoothing circuits at the secondary side of a power converting transformer.
CONSTITUTION: The secondary winding of a transfomer (Tr)18 is connected at both ends thereof to the anodes of diodes (D) 19, 21. The cathodes of the diodes 19, 21 are connected to the cathodes of dides 25, 26, respectively. The mid-point of the secondary winding 18s is connected to the anodes of the diodes 25, 26. The diodes 19, 25 form a rectifying circuit 27, and the diodes 21, 26 form a rectifying circuit 28. The circuits 27, 28 are connected at the output sides thereof through choke coils 31, 32, respectively to one terminal of a capacitor 23. The other terminal of the capacitor 23 is connected to the connecting point of the diodes 25, 26. The voltage applied to input terminals 11, 12 is rectified via the rectifying circuits 27, 28 at the secondary side of a transistor 18, smoothed via the choke coils 31, 32, and charged in a common capacitor 23. Thus, it can prevent the switching element from damaging, but operate it stably.
