Syxetc High Power Onboard DC/DC Converter For Tethered Drones 

Challenges faced by Tethered Drones Manufactors
This type of drone is powered and controlled through a cable connection to a ground power source.
Using high-voltage cable transmission from 500V to 800V can not only extend the cable length,
It also reduces the size of the wiring, allowing the drone to fly higher or travel further underwater.
Tethered UAVs usually require 1-5kW of ground power and are connected to a rotary-wing Unmanned Aerial Vehicle (UAV) or Unmanned Underwater Vehicle (UUV) through a cable.
This enables unlimited battery life and greater control capabilities.

Key goals include:

Optimized power supply via cables
Create a durable, highly integrated and reliable power supply system
Efficiently convert high voltage to safe 48V Safety Extra Low Voltage (SELV)

Syxetc solution
The power supply network (PDN) of the drone must be able to reduce the cable voltage with high efficiency and high power density,
without taking up valuable load space,
Syxetc high-power DC/DC converters are the most efficient way to convert high voltage into safe ultra-low voltage.

Dramatically reduces cable size, weight and drag
Easily convert high-voltage cables to safe ultra-low voltage busbars
Modular design meets flexible design needs
