The best solution of UAV power management scheme!
Uav power management
Power management refers to the efficient distribution of power to the different components of the system. Power management is critical for mobile devices that rely on battery power. By reducing energy consumption when components are idle, a good power management system can double or triple battery life. Power management technology is also known as power control technology.
At present, the main power management devices on the market mainly include separate power management chip PMIC and integrated power management unit PMU. Power Management Integrated Circuits (Power Management Integrated Circuits) is a chip that is responsible for the transformation, distribution, detection and other power management duties in an electronic device system. It is mainly responsible for identifying the CPU power supply amplitude, generating the corresponding short moment wave, and promoting the power output of the back-end circuit. Power management chips are available in both in-line and surface adhesive packages. The application range of power management chip is very wide, the development of power management chip is of great significance to improve the performance of the whole machine, the choice of power management chip is directly related to the demand of the system.
The scope of power management is relatively broad, including a separate power conversion (mainly DC to DC, that is, DC/DC), a separate power distribution and detection, and also includes a combination of power conversion and power management systems. Accordingly, the classification of power management chips also includes these aspects, such as linear power supply chips, voltage reference chips, switching power supply chips, LCD driver chips, LED driver chips, voltage detection chips, battery charge management chips, etc. If the designed circuit requires the power supply to have high noise and ripple suppression, requires a small PCB board area (such as mobile phones and other handheld electronic products), the circuit power supply does not allow the use of inductors (such as mobile phones), the power supply needs to have instantaneous calibration and output state self-check function, requiring the voltage drop of the regulator and its own low power consumption, low line cost and simple program, Then linear power supply is the most appropriate choice.
This power supply includes the following technologies: precision voltage reference, high performance, low noise operational amplifier, low voltage drop regulator, low static current. Power Management Unit (Power Management Unit) is a highly integrated power management solution for portable applications that integrates several traditional discrete power management chips and other devices in a single package, which can achieve higher power conversion efficiency and lower power consumption. And fewer components to accommodate reduced board space.
The role of PMU in UAV power management:
The more and more widespread use of PMU in UAV products, its most important role has the following points.
1. Provide stable and reliable power supply for each component of the UAV.
2.PMU helps to reduce the power consumption of the entire system and enables the drone battery to have a longer service life by reducing the energy consumption when the components are idle.
3.PMU has a good signal-to-noise rejection ratio and instantaneous response, which can better prevent the UAV from being affected by the external environment and achieve rapid instantaneous response.
4. The characteristics of PMU integration can save internal structure space, contribute to the miniaturization of products, and have better cost advantages as well as the unity and ordering of the entire system power supply system.
The PMU of the UAV ground remote control unit can supply power to each component to ensure the normal power supply of each component, and can filter the interference of external noise to a certain extent, better ensure the accuracy of the remote control, and at the same time, make the battery of the remote control use longer. The PMU power management module of the UAV flight control master control unit supplies power to all components, including the flight control master control unit and ESC electrical tuning unit, to ensure the normal and stable operation of the flight control unit.
