The discharge diode D1 is connected between the input terminal Vin of the three-terminal regulator 41 and the output terminal Vout. The output terminal 52 of the output interface 5 is connected to the adjustment terminal ADJ' of the three-terminal regulator 41. The output terminal 53 of the wheel-out interface 5 is connected to the power supply ground of the output terminal of the high-frequency rectification filter circuit 3. The output terminal 5 is not used as the positive terminal of the power supply of the AC power adapter, and the output voltage of the three-terminal regulator 41 is higher than the adjustment terminal by 1.25V. When an output plug 20 having an adjustment resistor is connected to the output interface 5, the wheel-in terminals 201, 202 and 203 of the output plug 2A are connected to the output terminals 51, 52 of the output interface 5. And 53. It is remotely connected between the output terminals 52 and 53, and is connected in series; and is connected in series between the positive pole of the power supply and the ground of the power supply of the AC power adapter. Since the voltage value of the output terminal Vout of the three-terminal regulator 41 is higher than the voltage value of the adjustment terminal of 1.25V, when the output plug 20 is connected to the output interface 5, the voltage value of the output end of the AC power adapter is passed through the formula V〇ut = l. 25 *(1+R/R1) is calculated. It can be seen from Fig. 3 and the calculation formula that the change in the resistance of the adjustment resistor causes the output voltage of the AC adapter to change accordingly. Then, by replacing the output plug, you can supply power to different electronic devices or charge the rechargeable battery of the electronic device. 096125579 Form No. A0101 Page 7 of 17 0993463918-0 1345358 December 28, 099 Shuttle Replacement Page [0013] See Figure 4. 4 is a circuit block diagram showing another embodiment of a multi-output AC power adapter body connected to an output plug according to the present invention.

An optocoupler isolating feedback circuit 7, a pulse width modulation controller 8 and an off circuit 9. When the adapter body 10 ′ is connected to the AC voltage source, the rectifying and filtering circuit 1 rectifies and filters the AC voltage into a DC voltage, and inputs the DC voltage into the transformer 2, and the transformer 2 is in the switch circuit 9 The DC voltage is step-down converted to obtain a low voltage DC ripple voltage, and the low voltage DC ripple voltage is input to the high frequency wall image circuit 3. The high frequency rectification filter circuit 3 sets the low voltage. The DC ripple voltage rectification filter: wave, and is regulated by the voltage regulator circuit 4' and then rotated through the output interface 51. The sampling circuit 6 samples the voltage value and the current value of the output interface 5, and the sampled voltage value and the current value are input to the pulse width modulation controller 8 via the optocoupler isolation feedback circuit 7, and the pulse width modulation is included. The controller '8 compares the sampled voltage value and the current value with the internal preset power, and outputs a control signal switching circuit 9 on and off according to the comparison result. The switching of the switching circuit 9 adjusts the output voltage of the transformer 2. As shown in FIG. 4, the voltage stabilizing circuit 4' includes a three-terminal regulator D102, a resistor R100, R101, and a capacitor C102. The anode of the three-terminal regulator D1 02 is connected to the power ground of the output of the high-frequency rectification filter circuit 3, and the cathode of the three-terminal regulator D102 is connected to the input terminal of the sampling circuit 6. The adjustment end of the three-terminal regulator D102 is connected to the positive terminal of the output end of the high-frequency rectification filter circuit 3 via a resistor R100. 096125579 Form No. A0101 Page 8 of 17 0993463918-0 1345358 [0015] On December 28, 099, the resistor R101 is connected in series with the capacitor C102 and then connected in parallel to the cathode of the three-terminal regulator D1G2. And the adjustment terminal' is used as the secondary side loop gain control. According to the characteristics of the three-terminal regulator D102, the adjustment voltage of the adjustment terminal is maintained at 1.25V. As can be seen from FIG. 4, the terminal 51 of the output interface 5 is connected to the resistor R100 and the output terminal of the high frequency rectification filter circuit 3, and the output terminal 52 is connected to the three-terminal regulator 〇1〇. The adjustment terminal of the second terminal is connected to the power ground of the output end of the high frequency rectification chopper circuit 3. The output terminals 51 of the output interface 5, "and" are used as the power supply positive terminal, the adjustment terminal, and the power ground of the AC power adapter, respectively. When the wheeled plug 20 is not inserted into the output interface: the output voltage of the AC power adapter is high frequency rectified green: f per output, the voltage of the terminal. When the turn-out plug 20 is inserted into the output interface 5, the wheel-in terminal 201 of the output plug 2〇 is connected to the terminal 51; the input terminal 202 of the output plug 2〇 is connected to the terminal 52.

If the output voltage of the AC adapter is v〇, then V0 can be calculated according to the formula v〇 = (i+ri〇〇/r)*i 25V. It can be seen from the calculation formula that when the resistance of the adjustment resistor R changes, the output voltage V0 of the AC trace adapter changes accordingly. The output plugs connected to different types of electronic devices are different, so the resistance of the adjusting resistors is different. Therefore, the user only needs to use the specific regulating power for the electronic device 096125579 Form No. A0101 Page 9 of 17 Page 0993463918-0 1345358 On December 28, 099, the output plug of the positive replacement page resistor R is connected to the adapter body 10' to obtain voltage and current suitable for the electronic device. In other embodiments, the adjusting resistor R can also be a resistor whose resistance is continuously adjustable. By adjusting the resistance of the resistor, the output plug 20 inserted into the output interface 5 can output a continuously varying voltage value, thereby satisfying Different voltage requirements for electronic equipment.
