Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments, is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of suitable modules power supply gives super capacitor charging circuit, including power module 1 and virtual negative
2 are carried, L and N the input termination of the triple line of power module 1 connect with the alternating voltage of 220V, the output end+Vo of modular power source 1

By stabilization；Dummy load 2 is unloaded, does not make completely, is in standby shape.
Super capacitor C1 powers to dummy load 2 simultaneously from fully charged rear and modular power source 1, and the capacitive of super capacitor C1 is non-
Chang great, the electric energy stored is very more, while the very small even 0A of electric current needed for dummy load 2, due to modular power source 1
Concussion that very sensitive, so big capacitance necessarily draws modular power source 1 that be to capacitive dummy load 2 be, is directed at module electricity
1 output voltage of source is unstable, is finally directed at the unstable of circuit work, and it can be seen from above-mentioned 2 working condition of dummy load
As long as in output end one resistance R1 of parallel connection of modular power source 1, the false dummy load as modular power source 1 can solve this and ask
Topic.
Fig. 2-6 is please referred to, is in series with relatively good advantage, scheme 2,3,4 such as the super capacitors multiple for solution of scheme 1
The charging modes of single or multiple super capacitors in parallel are solved, but these circuits are more complex, higher cost, and actually has the bustling noise of a market
On field shown in common Fig. 6, the characteristics of this circuit be it is simple, it is at low cost, in this circuit, if super capacitor C1 capacity
If big, due to be modular power source it is output terminal direct paralleled together, this circuit can be made unstable.
In conclusion this suitable modules power supply gives super capacitor charging circuit, as the logical upper 220VAC of 1 input terminal of modular power source
When, with the extension of time, the voltage on super capacitor C1 is begun to ramp up from 0V, the electric current of super capacitor C1 becomes smaller at leisure,
