7A and 7B are circuit diagrams showing two embodiments of the voltage stabilizing circuit of the present invention, respectively. The main function of the voltage stabilizing circuit of the present invention is to convert the electrical energy stored in the electric double layer capacitor into a stable voltage output. The voltage stabilizing circuit shown in Figures 7A and 7B is for illustration only, and those skilled in the art will appreciate that other embodiments may be employed to implement the voltage switching requirements.

In FIG. 7A, the voltage stabilizing circuit 6 is mainly composed of an LDO (Low Drop-out type regulator) chip 100, a filter capacitor C1, an output phase compensation capacitor C2, and a PNP tertiary tube T1. The filter capacitor C1 is connected between the In (input) pin and the Vss pin of the LDO chip 100, and is connected in parallel with the above-described electric double layer capacitor 5. The output phase compensation capacitor C2 is connected between the Out (output) pin and the Vss pin of the LDO chip 100. The Vss pin is grounded. The base of the PNP transistor T1 is connected to the Ext (external) leg of the LDO chip 100, the emitter is connected to the In pin of the LDO chip 100, and the collector is connected to the Out pin of the LDO chip 100. The set voltage is determined by the selected LDO chip. The LDO chip can convert the input voltage Vin within the specified range of the specification into a set voltage stable output. When the input voltage is greater than the set voltage, the output voltage Vout is equal to the set voltage; when the input voltage Vin is less than the set voltage, the output voltage Vout changes in accordance with the input voltage change. The function of the PNP transistor is to amplify the output current. Some LDOs (such as the Seiko model S1172 LDO) can output large currents themselves, eliminating the need for an external PNP transistor. Since the electric double layer capacitor connected to the input end of the voltage stabilizing circuit is itself an oversized capacitor, In the present invention, the filter capacitor C1 at the input can also be omitted.

In Fig. 7B, the voltage stabilizing circuit 6 is mainly composed of a DC/DC DC voltage conversion chip 200, an inductor L, a current driving three-stage tube T2, a Schottky diode D, and a filter capacitor C3. Wherein one end of the inductor L is connected to the positive pole of the electric double layer capacitor, and the other end is connected to the collector of the current driving transistor T2. The emitter of the current-driven transistor T2 is grounded, and the base is connected to the Ext (external) leg of the DC/DC DC voltage conversion chip 200. The Vss pin of the DC/DC DC voltage conversion chip 200 is grounded, and the filter capacitor C3 is connected between the Out (output) pin of the DC/DC DC voltage conversion chip 200 and the Vss pin. The anode of the Schottky diode D is connected to the collector of the transistor T, and the cathode is connected to the Out leg of the DC/DC DC voltage conversion chip 200. The DC/DC DC voltage conversion chip 200, in combination with other required components, converts a range of input voltages into a stable voltage output. However, when the input voltage Vin is lower than the input startup voltage of the chip, the output voltage Vout is not output.

The power supply of the product is especially suitable for small appliances such as electric shavers, electric toothbrushes, LED flashlights and other single-use time.
