How can a high power density converter meet low losses and high frequency specifications?
In order to meet low losses and high frequency specifications of a high power density converter, more constraints are applied to the converter’s filter design, especially concerning the inductor design.
What is a high power density inverter?
HIGH POWER DENSITY INVERTERS A. Three phase inverters trade-offs Inverters are used in aircraft systems to convert a portion of the aircraft's DC power into AC. This AC power is used mainly for instruments, radio, radar, lighting, air conditioning, actuation systems and other accessories.
Which amorphous inductor has the highest weight?
Considering the curves at 20 kHz and at high current ripple, the amorphous inductor has the highest weight followed by the FeSi inductor given their high core losses which can only be dissipated with a large surface.
Are low-cost inverters efficient?
On the other hand, low-cost designs are rarely efficient. High power density of the inverter implies a very constrained design of the output filter. Furthermore, all losses in the power conversion are to be reduced, in order to increase efficiency. On the other hand, the cost must obviously be maintained at a reasonable level.
