Then, power converted into direct current by a bridge rectifier circuit constituted by rectifiers 6, 7° 8.9 and a smoothing capacitor 12 is supplied to a load 13 from a positive terminal 1o and a negative terminal 11. However, in the conventional configuration as described above,
In order to increase the voltage supplied to the load 13 when the load is light, it is necessary to increase the number of secondary turns of the transformer 3 to increase the no-load voltage and increase the music power. , When the load 13 is heavily loaded, the copper loss of the transformer 3 is large, so the amount of heat generated increases, and the transformer 3 is destroyed by the heat.In order to prevent destruction due to this heat, the transformer 3 must be made larger. There was a problem.

くならない。Reference numerals 1 to 13 in FIG. 2 are the same components as in FIG. 1, and their explanations will be omitted. 14 is a half-wave voltage doubler capacitor whose positive side is connected to the terminal 4 of the transformer 3, and whose negative side is connected to the anode of the rectifier 15 and the cathode of the rectifier 160. The anode of the rectifier 16 is connected to the terminal 5 of the transformer 3, and the cand of the rectifier 15 is connected to the positive terminal 10 via a resistor 17. If the capacitor 14 and rectifiers 15 and 16 constitute a half-wave voltage doubler circuit and connect it in parallel to the bridge current circuit, when the load 13 is light, the AC voltage wave appearing at the terminals 4 and 6 of the transformer 3 will be Since the high value is high, a half-wave voltage doubler circuit operates,
Increase the DC voltage appearing at output terminals 10 and 11. load 1
If 3 is heavy, the peak value of the AC voltage coming out to terminals 4 and 5 of transformer 3 will be low, so even if the half-wave voltage doubler circuit operates, the DC voltage appearing at output terminals 10 and 11 will be too high. No.
