01 / LOSSESMap heat generation

Separate semiconductor, magnetics, capacitor and conductor losses.

02 / PATHEngineer heat spreading

Interfaces, baseplates and coolant paths determine temperature rise.

03 / AIRCRAFTUse real cooling conditions

Airflow and ambient assumptions must match installation.

04 / VALIDATEInstrument critical points

Verify temperatures under representative mission cycles.

Power density cannot be separated from cooling

Reducing enclosure volume changes heat flux, component spacing and serviceability. A mass target should therefore be reviewed together with electrical losses and the available aircraft cooling method.

Model interfaces, not only components

Thermal resistance can be dominated by pads, fasteners, baseplates, contact pressure and local airflow. These interfaces need controlled assumptions and repeatable assembly.

Engineering data policy: project limits and verified results are released only for the configuration they represent.

Validate against the mission cycle

Steady-state testing is necessary but may not reveal repeated peak-power heating. Validation should include representative ambient conditions and transient sequences for the frozen configuration.

Define the system boundary before freezing the hardware.

Golden Phoenix reviews electrical architecture, control, communication, mechanical integration and validation as one project configuration.

Inputs for technical review

  • Ambient and altitude envelope
  • Continuous and repeated peak losses
  • Available airflow or liquid cooling
  • Maximum component and case temperatures
  • Mounting-interface thermal resistance
  • Sensor positions and derating strategy

Engineering FAQ

What defines Thermal Design for High-Power UAV DC/DC Converters?

Airborne power density is a system tradeoff. Semiconductor, magnetics and conductor losses must reach the aircraft environment through a thermal path that remains credible across altitude, ambient temperature and mission duration.

Which information is required before configuration?

Ambient and altitude envelope; Continuous and repeated peak losses; Available airflow or liquid cooling; Maximum component and case temperatures; Mounting-interface thermal resistance; Sensor positions and derating strategy

Are performance numbers fixed for every project?

No. Golden Phoenix releases efficiency, mass, thermal and dynamic-response values only for a confirmed project configuration.
