6 show results from selected conductive and radiated emissions tests. transient suppression: the input voltage surge and spike compliance matrix displays the worst case requirements listed in various 28v military (vehicle and aircraft) and civil aircraft standards. the mcots-f-28-t emi filter is designed to handle all of the short duration voltage spike requirements of these standards (with certain assumptions regarding def-stan 61-5). some of the long duration voltage surge requirements remain within the 50v maximum transient rating of a synqor mcots-c-28 dc/dc converter. the others require the transient suppression circuitry of the mcots-f-28-t emi filter to protect the converter from an over-voltage condition. if mcots-c-28e or mcots-c-28ve converters are used, voltage surges as high as 80v can be tolerated without the need for this transient suppression circuitry. the mcots-f-28-t emi filter is also designed to pass the waveform types and applications specified in rtca/do-160e section 22 (lightning induced transient susceptibility) to level 4. reverse polarity protection: the mcots-f-28-t emi filter has a series-connected mosfet that is controlled to function as a diode, but with a very small forward voltage drop ( 4 m x iout). this synchronous rectifier blocks reverse current flow if the filters input voltage is mistakenly connected with the wrong polarity. the anti-parallel diode, working with the synchronous rectifier, ensures that the filters output voltage goes only slightly negative during this time, and therefore satisfying the minimum input voltage specifications of synqors mcots converters. the synchronous rectifier also performs a useful function during negative polarity spikes and surges, and during brief power interrupts. since it stops current from flowing negatively through the emi filter back toward the source, the synchronous rectifier allows the total bulk capacitor (located both within and external to the filter) to better hold up the output voltage during these transients. on/off: the mcots-f-28-t filter has enable pass-through circuitry that bridges an enable signal across the filters common-mode impedance. the on/off input pin (pin b) is referenced with respect to the filters input return (pins 3 and 4). the on/off output pin (pin 8) is referenced with respect to the filters output return (pin 5). the input return and output return may have a different voltage due to common- mode noise and transients. note: during the time that the mcots-f-28-t filter is in its soft- start mode the on/off output will be held at a logic low. this is done so that all of the filters loads can be disabled by this signal during the soft- start period. once the soft- start is completed, on/off output will follow on/off input. figure a shows the equivalent circuit looking into on/off input. the on/off input pin must be pulled low to turn an mcots converter off. it may be left open-circuit to turn the converter on. figure b shows the equivalent circuit looking into on/off output. the n-channel mosfet in this circuit turns on when power is applied to the filter and on/off input is low. otherwise, the mosfet is off. standard mcots converters are enabled when their on/off pin is held low. to interface the enable output of the mcots-f-28-t filter with mcots converters, add a n-type mosfet as shown in the typical connection diagram. for improved noise tolerance, a seperate mosfet can be used for each mcots converter, with their gates isolated from each other with sense resistors. 2 n 3904 1 n 4148 250 k 125 k 82 k 5 . 6 v to enable circuitry pin b ( on / off input ) pins 3 and 4 ( input return ) 33 nf figure a: equivalent circuit looking into the on/off input pin with respect to the input return pin.
