The circuit of meter on unmanned plane for improving the demand.
In addition, the circuits such as most of voltage managements or transformation can all design a very small display element intuitively to show
Situations such as showing variation in voltage or surplus, although this design can bring great convenience to user of service, if it is
For UAV system, this design just seems less necessary, because unmanned plane is either below high-altitude or tunnel
All it is that user of service is difficult to the place reached at the first time.On the other hand, as winged control test side, there are remote controler or ground more
Stand and detect cell voltage service condition, under-voltage protection action is also equipped with flying control --- it hovers or makes a return voyage.

Electric power management circuit can be roughly divided into input processing, voltage transformation, output processing three parts composition.Wherein, voltage
Transformation is most important part, it includes wide-range voltage processing, voltage is unitization, the control of output end electric resistance partial pressure is defeated
Go out.
Specifically, circuit is mainly made of integrated chip XL4015E1 and associated external circuit, and wherein XL4015E1 is
One switching buck DC-DC conversion chip；Fixed switching frequency 180KHz can reduce external component size.Chip has
Outstanding line regulation and load regulation is inputted for DC8V~36V, and output voltage is supported arbitrarily to adjust between 1.25V~32V
Section, the decompression constant pressure application of output maximum current 5A, highest transfer efficiency can reach 93%.Chip interior integrates overcurrent and protects
The reliability modules such as shield, overheat protector, short-circuit protection.There are five pins by the XL4015E1 encapsulated using TO263-5L, 1.： GND
The Schottky diode that the pin should be placed prevents switching current peak voltage noise-induced in output capacitance grounding path
xl4015；②：FB simultaneously adjusts it by a non-essential resistance potential-divider network, FB detection output voltages, threshold voltage 1.25V
Feedback；③：SW is the switching node that power supply is provided to output；④：VC internal voltage regulator shunt locations.In typical system
Using VC pins connect the ability VIN of a 1uF；⑤：VIN supply voltage input pins.XL4015E1 is in 8V to 36V direct currents
Voltage.VIN to GND and a bulky capacitor appropriate are bypassed, to eliminate the input of noise.
In continuous mode, the input current of converter is the square wave that one group of duty ratio is about VOUT/VIN.In order to prevent
Big transient voltage, it is necessary to select low ESR (equivalent series resistance) input capacitor using being required for maximum RMS current.
For mostly applying, the input capacitor of 1 10uF is sufficient, its placement location is as close to the position of XL4015
It sets.Maximum RMS (root-mean-square value) electric current of input capacitor is given by：

Low ESR capacitances should be selected to reduce output ripple voltage in output end, in general, once capacitance ESR is expired
Foot, capacitance are just sufficient for demand.The ESR of any capacitor will be that system generates a zero, ESR values together with its own capacity
Bigger, the frequency band that zero is located at is lower, and the zero of ceramic condenser is in a higher frequency, is a kind of excellent choosing
It selects, but compared with electrolytic capacitor, large capacity, high voltage ceramic condenser meeting volume are larger, and cost is higher, therefore extremely using 0.1uF
It is good selection that the ceramic condenser of 1uF is used in combination with low ESR electrolytic capacitors.Output voltage ripple is determined by following formula：
F in formula indicates that switching frequency, COUT indicate that output capacitance, △ IL indicate the ripple current in inductor.
Although inductor has no effect on working frequency, inductance value has direct influence, inductance line to ripple current
Wave electric current △ IL reduce with the increase of inductance value, and increase with the raising of VIN and VOUT.For setting ripple current
A logical starting point be △ IL=0.3*ILIM, wherein ILIM be peak switch current limit value.In order to ensure ripple current
In a defined maximum value hereinafter, should inductance value be selected as the following formula：

Flow 5A and backward voltage 40V.Typical forward voltage is 0.55V under 4A electric currents.The diode only has electric current during switch OFF
It flows through.Peak inverse voltage is equal to the input voltage of voltage-stablizer.In normal work, mean forward current can calculate as follows：
The present invention is directed to unknown working environment, and automatic obstacle avoiding flies the environmental factor of unmanned electromechanical source, using XL4015E1
Chip, chip interior integrate the reliability modules such as overcurrent protection, overheat protector, short-circuit protection.The peripheral circuit integrated level of design
Height, peripheral components are few so that debugging and use are more convenient.Relative to other voltage changing modules such as LM2596, MP1584en,
Using XL4015 there is the electric current of bigger to export, then the electrical power of the module is both greater than other electric current transformations under same voltage
Module.Different according to the camera types that unmanned plane usage scenario is different and needs, adjustable voltage exports all the way for setting, reaches
Wide range input, adjustable voltage export purpose；It can solve to set due to shadow because of unsmooth or not independent supply line simultaneously
Ring the problem of camera image transmission makes Aerial vehicle position be affected with flight.
As shown in Fig. 2, the present invention the course of work approximately as：It is divided into 5 major parts on the whole to be handled, point
It is not that input is pre-processed, is filtered, based on XL4015DC-DC transformations, output voltage stabilizing and development board output processing.
Input is that 8V-36V potential circuits are filtered first, and coupled capacitor, the most important part of circuit is added
XL4015 is fixed-frequency PWM decompression (decompression) DC-DC converter of 180kHz, can high efficiency drive 5A loads, have
There are low ripple and outstanding circuit and load regulation.Minimal number of outer member is needed, adjuster uses simply, including inside
Frequency compensation and fixed oscillator.
Pwm control circuit can adjust duty ratio linearly from 0 to 100%.One in built-in current protecting function.As short guarantor
When protective function occurs, operating frequency will be from 180khz to 48kHz.Internal compensation block is built-in, to reduce outer member to the greatest extent
Quantity.
By feedback pin FB again by non-essential resistance divider network, FB sensing output voltages simultaneously adjust it for output.It is defeated
The value for going out voltage is：
VOUT=1.25* (1+R2/R1)
The invention also discloses a kind of power management plates for small and medium size unmanned aerial vehicles exploitation, and by-passing type is used to design,
And the power management plate has previously described electric power management circuit.It is one by battery design to input via management circuit again
Output is multichannel, changes battery and directly splits into multichannel, and each output is all independent and does not influence battery, improves system decoupling
Property.The design not shown using usual band, can not only reduce energy loss but also be greatly reduced integrated circuit board
Area, is more suitable for the application characteristic of unmanned plane, also makes unmanned plane appearance design and packaging more convenient.It is solved in addition, concentrating
