How does altitude affect power electronics design?Let’s review the physics involved in power electronics design. As altitude is increased, the air is less dense. The cooling capacity of the air decreases as altitude increases (decreased density) making heat removal via air less effective. Additionally, according to Paschen's Law the dielectric properties of air change with altitude.
Does convection affect the temperature of electronics at high altitudes?Therefore, all electronics that rely on natural or forced convection to dissipate heat will experience greater air and component temperature rises for the same amount of power at high altitudes Paschen curves illustrate the dependency of breakdown voltage on distance between conductors and altitude.
Why is meteorological data important for a power supply solution?For a power supply solution that uses renewable energy, meteorological data are important in order to properly size and optimize the power supply system for the off-grid BS.
How to design an ideal power supply solution?The key aspects in designing an ideal power supply solution are reviewed, and these mainly include the pre-feasibility study and the thermal management of BSs, which comprise heating and cooling of the BS shelter/cabinets and BS electronic equipment and power supply components.
What is a high voltage power supply?Voltages, steady-state or repeated transients higher than 327V are referred as high voltages. Power supplies routinely have 240-265 VAC and 380 or more VDC internally, as well as high-frequency high voltage AC energy. Thus, considerations for breakdown and processing high voltage must be considered for use in the end application.
How does altitude affect cooling capacity?As altitude is increased, the air is less dense. The cooling capacity of the air decreases as altitude increases (decreased density) making heat removal via air less effective. Additionally, according to Paschen's Law the dielectric properties of air change with altitude. The creapage and clearance of the power supply has to take this into accou
