Active filter protects DC-DC converters in harsh environments

17 October 2007 Circuit & System Protection

XP Power has released a new 500 W active filter unit for use in harsh electrical environments. The DSF500 is designed to protect DC-DC converters from the surges, spikes and ripples that are typically found on the electrical system of any military platform, such as an aircraft or vehicle. The filter meets the military specification MIL-STD 1275A-D, without the need to incorporate any additional components. This allows platform mounted systems to utilise standard industrial DC-DC converters without risk of failure or damage due to supply transients and noise. Input voltage is within the range of 10 to 34 V d.c., while output voltage is tracked and clamped to below 36 V d.c.

The DSF500's low loss, MOSFET-based protection circuit ensures that the unit can provide continuous reverse voltage protection. Attached systems are protected from incorrect, potentially damaging, electrical supply connections. The filter also protects against over-current conditions; should the demand exceed 28 Amps, a warning signal is given that can be used either to disable the DSF500 or turn off the attached devices in order to reduce the current. A disable function allows the system designer to turn off the unit remotely if required.

The unit measures 57,90 x 57,90 x 16, 45 mm. Compliance to electromagnetic immunity MIL-STD 461E specification can also be achieved with some design effort.
