BASIC OPERATION FEATURES
MQME-28E-T6 multi-stage differential-mode commonmode passive filter designed interface power source with more SynQor DC/DC converters other loads that create EMI). Each stage this filter well damped avoid resonances oscillations, only multi-layer ceramic capacitors used. Figure shows typical differential common-mode attenuation provided this filter when source impedance chassis ground each input line. MQME-28E-T6 filter includes large bulk capacitor (also X7R) with series damping resistor correct unstabilizing effect converter's negative input resistance. white paper discussing this negative input resistance need corrective damping found SynQor website (see Input System Instability application note). Figure shows magnitude filter's output impedance when filter input connected stiff voltage source. When used with SynQor's DC/DC converters, MQME-28E-T6 filter designed pass relevant MIL-STD-461C/D/E requirements their most stringent limits. MIL-STD-461 Compliance Matrix Table lists these requirements describes setup used pass them. Figures show results from selected conductive radiated emissions tests.
Technical Specification
MQME-28E-T6 Current:
synchronous rectifier also performs useful function during negative polarity spikes surges, during brief power interrupts. Since stops current from flowing negatively through filter back toward source, synchronous rectifier allows total bulk capacitor (located both within external filter) better hold output voltage during these transients. ENABLE: MQME-28E-T6 filter enable pass-through circuitry that bridges enable signal across filter's commonmode impedance. ENABLE INPUT (pin referenced with respect filter's INPUT RETURN (pins ENABLE OUTPUT (pin referenced with respect filter's OUTPUT RETURN (pin INPUT RETURN OUTPUT RETURN have different voltage commonmode noise transients.
NOTE: During time that MQME-28E-T6 filter SoftStart mode ENABLE OUTPUT will held logic low. This done that filter's loads disabled this signal during Soft-Start period. Once Soft-Start completed, ENABLE OUTPUT will follow ENABLE INPUT. Figure shows equivalent circuit looking into ENABLE INPUT. ENABLE INPUT must pulled turn MQFL converter off. left open-circuit turn converter

TRANSIENT SUPPRESSION: input voltage surge spike compliance matrix displays worst case requirements listed various Military (Vehicle Aircraft) Civil Aircraft standards. MQME-28E-T6 filter designed handle short duration voltage spike requirements these standards (with certain assumptions regarding DEF-STAN 61-5). Some long duration voltage surge requirements remain within maximum transient rating SynQor MQFL-28 DC/DC converter. others require transient suppression circuitry MQME-28E-T6 filter protect converter from over-voltage condition. MQFL-28E MQFL-28VE converters used, voltage surges high tolerated without need this transient suppression circuitry. MQME-28E-T6 filter also designed pass waveform types applications specified RTCA/DO-160E Section (Lightning Induced Transient Susceptibility) Level Section Compliance Matrix Table lists these waveforms applications describes setup used pass them.

This "Synchronous Rectifier" blocks reverse current flow filter's input voltage mistakenly connected with wrong polarity. anti-parallel diode, working with synchronous rectifier, ensures that filter's output voltage goes only slightly negative during this time, therefore satisfying minimum input voltage specifications SynQor's MQFL converters.

MQME-28E-T6 Current:
STANDBY: MQME-28E-T6 filter standby circuitry that minimizes power drawn from filter's input power source when standby feature activated. does this ways. First, output filter disconnected from input that there will power drawn downstream converters other loads. Second, active circuitry within filter placed into reduced power consumption mode. result current draw only about from input power source.
Figure Equivalent circuit looking into ENABLE OUTPUT with respect OUTPUT RETURN pin.
Once input voltage exceeds turn-on threshold value, Soft-Start circuitry controls filter's output current approximately 1.6A. This mode operation continues until filter's output voltage reaches input voltage, which time filter able deliver rated output current. after SoftStart duration period filter's output risen input voltage, then filter will disconnect output from input, wait time equal Soft-Start recycle period, initiate Soft-Start.
Figure shows equivalent circuit looking into STANDBY (pin
This referenced with respect filter's OUTPUT RETURN (pin should pulled have filter operate normal mode. instead left open-circuit pulled high internal circuitry, standby feature will activated. Application Note: typical application would place MQME filter close input DC/DC converter, with cases filter converter connected together through ground plane. Both cases electrically conductive, connection cases made with fasteners used secure device. connect outputs multiple MQME-28E-T6 filters parallel. Connecting filters this manner result slightly unequal currents flow positive return paths each filter. These unequal currents cause internal commonmode chokes saturate thus cause degraded common-mode rejection performance.
Since, during Soft-Start, filter will deliver only 1.6A output, important limit load current that total bulk capacitance fully charged before Soft-Start duration period over. facilitate this, filter's ENABLE OUTPUT held during Soft-Start mode. This signal therefore used disable filter's loads during this time. Once SoftStart mode completed, ENABLE OUTPUT will follow ENABLE INPUT. OUTPUT POWER LIMIT: MQME-28E-T6 filter output power limit feature protect against short circuit output pins. This limit disabled whenever output voltage rising that will encountered when charging output capacitance. When output power exceeds ~450W output voltage decreasing however, this feature will turn filter reinstitute soft-start cycle 500ms. Figure shows output power limit threshold function output voltage.
