In addition to objects, features and advantages described above, the utility model also has other purposes, feature and excellent
Point.Below with reference to figure, the utility model is described in further detail.
Brief description of the drawings
The accompanying drawing for forming the part of the application is used for providing further understanding to of the present utility model, of the present utility model
Schematic description and description is used to explain the utility model, does not form to improper restriction of the present utility model.
Fig. 1 is the circuit theory figure from the power supply of energy storage inductor secondary of the utility model embodiment；
Fig. 2 is traditional linear switch pipe voltage stabilizing power supply mode circuit.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
With reference to figure 1, as shown in Figure 1 is a kind of from the loop of energy storage inductor secondary power supply, including energy storage inductor T1, rectification two
Pole pipe D, electrochemical capacitor EC, resistance R, ground capacity C, control chip IC；The commutation diode D positive poles connection energy storage inductor T1
Output end, negative pole connect electrochemical capacitor EC positive poles, resistance R, ground capacity C, control chip IC respectively；The electrochemical capacitor EC is born
Pole connection ground；The resistance R other ends connection ground.
The electrochemical capacitor EC is the electric capacity to filter.
Energy storage inductor T1 produces high-frequency ac voltage using secondary coil mutual inductance magnetic principles, through D rectifies
DC voltage is adjusted to, the voltage of its small part alternating component is filtered out by EC electrochemical capacitors, R mainly provides certain electric current,
So that output voltage will not wave, it is more stable to meet the needs of giving control chip power supply.
To improve electricity shortage of starting shooting, over the ground one charge and discharge capacitance C of GND parallel connections.
Fig. 2 circuits are traditional linear switch pipe voltage stabilizing power supply mode circuits.It act as：Switched using mosfet former
Reason, give ZD voltage-stabiliser tubes by R21 when Vbus voltages and one bias voltage is provided, when reaching Q cut-in voltage Vth=2.5v
At this moment Q is turned on for conducting, and Q S poles output 5v, ZD are voltage-regulator diode (if output 5.0v), when G voltage surmounts 5v, immediately
GND is conducting to, remains that 5v voltage gives IC power supplies.Electric capacity C effect is filtering noise information composition.
Compared to Fig. 2, current supply circuit of the present utility model, reduce product ontology space, can meet that product minimizes market need
Ask；Product cost is saved, lifts product cost；Its output voltage is similarly steady by the way of the secondary power taking of energy storage inductor
It is fixed, the simple efficiency high of circuit.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
