DC-DC converter for aerospace, defense, and civil aviation electronics applications introduced by Modular Devices
SHIRLEY, N.Y., 19 Jan. 2014. Modular Devices Inc. (MDI) in Shirley, N.Y., is introducing the series 3090 compact DC-DC converter for aerospace, defense, and civil aviation airborne electronics applications.
The power electronics device meets MIL-STD-461 D, E and F without need for external EMI filtering, and enable efficient compliance with electromagnetic interference compatibility (EMC) requirements for aerospace and defense applications.
The series 3090 5-watt DC-DC converters operate from nominal 28-volt DC power sources. Models are available with single or dual outputs, and are packaged in a hermetic case that measures 1.08 inches square by 0.380 inches.
The 3090 design can operate through MIL-STD-704A 80V/100mS power line transients.
DC-DC converters generate EMI, company officials say. When the package is small, close proximity can present a formidable challenge that is overcome by the 3090 design.
EMI filters also have areas of resonance that can amplify unwanted AC components superimposed on the DC input. Resistance to this effect is tested by MIL-STD-461 conducted susceptibility tests.
Simple LC EMI filters often have a large resonance that can cause unwanted AC ripple on the output. However, the Model 3090 has a damped EMI filter design, giving performance in rejection of conducted susceptibility (MIL-STD-461 revisions D, E, and F method CS101 and CS102) inputs.
