UAVs are widely used in various industries and fields due to their advantages such as no human intervention and rapid deployment. However, the UAV has a short flight time. This shortcoming limits the large-scale application of UAVs. Most drones use airborne rechargeable lithium batteries, which rarely last for more than one hour. However, in some fields, such as emergency communications, on-site monitoring, on-site command and other fields, drones are required to be left empty for long periods of time. Therefore, UAVs powered by ground power through wires, that is, tethered UAVs, came into being. Tethered UAV systems are generally divided into a ground part and an air part. The two parts are connected by cables. The ground part is generally composed of power and control parts, and the air part is generally composed of batteries, fuselage, sensors and other parts.
Compared with other types of UAVs, tethered UAVs can stay in the air for a long time without being limited by electric energy because of the existence of cables. It has obvious advantages in emergency communication, high-altitude monitoring, environmental monitoring and other scenarios, and can be fixed. Installation or vehicle installation and can move with the vehicle. Tethered drones are expensive to build and the application scenarios are more complicated. Once the power system has a problem, it is likely to cause damage to the precision sensing or flight control system on the aircraft, and in some cases there is a risk of crashing. In order to avoid the occurrence of high losses, the engineers who designed the drone have put forward higher requirements on the quality of the
Power Supply. After multiple comparison tests, a drone manufacturer engineer finally chose APM high-power
DC Power Supply.
APM high-power DC power supply has high power density, high reliability, high precision, perfect operation port, and internal integration of powerful test functions, which can more comprehensively cover the various test requirements of users to simulate various products The normal and abnormal working environment and the measurement of important electrical parameters provide a high-quality guarantee for the quality of customers' products.
