Overpower supply lines, DC-DC converters produce conducted emission noise. Due to the reduced filter component size and BOM cost, many DC/DC converter ICs incorporate a spread spectrum function that reduces noise.
But an DC-DC input filter is necessary to truly cut the level of conducted emissions to a level that is acceptable.
Input filter design and usage for DC/DC converters are both taken into account in this application note.
The DC/DC converter's input current flow alternates with the switching frequency of the converter. Due to the alternating input current flow, the input capacitor attached to a converter IC input has an equivalent series resistance (ESR) that causes voltage ripples.
The ESR of the employed capacitor mostly determines how much of a voltage ripple occurs.
The ESR of electrolytic and polymer capacitors is comparatively high. When these types of capacitors are in use, the voltage ripple's value might vary from a few milliohms to several ohms.
On the other hand, multilayer ceramic capacitors (MLCCs) have an extremely low ESR of just a few milliohms, resulting in a noise voltage of a few millivolts.
An oscilloscope can be used to study the AC components at the DC/DC converter's input while performing a time-domain analysis.
This makes it easier to measure any interference spectrum during the DC/DC converter design process and offers a quick approach to calculate any conducted emissions or EMC concerns.
The Global DC-DC input filter market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
P-DUKE has introduced a DC-DC input filter, the new MCF series, which are front-end filters for P-DUKE COTS (commercial-off-the-shelf) DC/DC converters to conform with MIL-STD 1275D's criteria for the characteristics of 28 volt DC electrical systems in military vehicles and MIL-STD 461.
(Requirement for the control of electromagnetic interference characteristics of subsystems and equipment).
This filter series can handle input voltages of 9â36Vdc (50Vdc for 1 second), making it appropriate for military vehicles with 28V bus systems or 24V bus systems. They can be used for rolling stock as well as large industrial applications.
