6 BASIC OPERATION AND FEATURES The MQME is a multi-stage differential-mode and commonmode passive EMI filter designed to interface a power source with one or more SynQor DC/DC converters (or other loads that create EMI). Each stage of this filter is well damped to avoid resonances and oscillations, and only X7R multi-layer ceramic capacitors are used. Figure shows the typical differential and common-mode attenuation provided by this filter when the source impedance is 50Ω to chassis ground on each input line. The MQME EMI filter includes a large bulk capacitor (also X7R) with a series damping resistor to correct for the unstabilizing effect of a converter s negative input resistance. A white paper discussing this negative input resistance and the need for corrective damping can be found on the SynQor website (see Input System Instability application note). Figure 2 shows the magnitude of the filter s output impedance when the filter input is connected to a stiff voltage source. The input voltage surge and spike compliance matrix displays the worst case requirements listed in various 28 Military (ehicle and Aircraft) and Civil Aircraft standards. The MQME EMI filter is designed to handle all of the short duration voltage spike requirements of these standards (with certain assumptions regarding DEF-STAN 6-5). Some of the long duration voltage surge requirements remain within the 50 maximum transient rating of a SynQor MQFL-28 DC/DC converter. The others require the transient suppression circuitry of an MQME-28-T EMI filter to protect the converter from an overvoltage condition. If MQFL-28E or MQFL-28E converters are used, voltage surges as high as 80 can be tolerated without the need for this transient suppression circuitry. L I SN Source 50Ω I meas in(+) When used with SynQor s DC/DC converters, the MQME EMI filter is designed to pass all of the relevant MIL-STD-6C/D/E/F requirements to their most stringent limits. The MIL-STD-6 Compliance Matrix Table lists these requirements and describes the setup used to pass them. Figures - 6 show results from selected conductive and radiated emissions tests. The filter is also designed to pass the waveform types and applications specified in RTCA/DO-60E Section 22 (Lightning Induced Transient Susceptibility) to Level (some waveforms/ applications require the MQME-28-T filter and/or external transient suppression circuitry). The Section 22 Compliance Matrix Table lists these waveforms and applications and describes the setup used to pass them. A typical application would place the MilQor filter close to the input of the DC/DC converter, with the cases of the filter and the converter connected together through a ground plane. Both cases are electrically conductive, so connection to the cases can be made with the fasteners used to secure the device. Do not connect the outputs of multiple MQME filters in parallel. Connecting filters in this manner may result in slightly unequal currents to flow in the positive and return paths of each filter. These unequal currents may cause the internal common-mode chokes to saturate and thus cause degraded common-mode rejection performance.

Input Return pin connected to system ground Signal applied to unshielded power cable bundle Signal applied between metal ground plane and system ground Signal applied to unshielded power cable bundle Met by an MQME Filter having the Transient Suppression and Reverse Polarity Protection Features * Requirement is deemed to have been met as long as transient deviations in the converter s output voltage remain within ±0% of its initial value. For these waveforms at Level and above, an external transient suppressor of sufficient energy rating must placed across the filter s input pins to keep the differential transient input voltage below +200/-50. Negative polarity waveforms may cause power flow to the converter to be interrupted long enough to cause a graceful shutdown and restart of the converter. Also, the reverse voltage protection feature of the -T filter is required to protect the converter (but not the filter) from negative polarity waveform. ** For this waveform at a Level and above, external transient suppressors of sufficient energy rating must be added between the filter s input power pins and its case to keep the common-mode transient input voltage below Page 8

These are defined as the maximum disturbances that equipment can inflict upon the power system, not as disturbances imposed upon utilization equipment. To ensure compatablitily, however, these are within the designed stress envelope of the indicated filters & converters. For the DEF STAN 6-5 specification: ) Negative surges require reverse voltage protection circuitry to protect the converter (but not the filter) from a negative input. This circuitry is included in the MQME-28-T but not the and MQHE-28-P filters. 2) The negative surges may cause the converter to shut down unless additional holdup capacitance is included. ) Maximum spike voltages are assumed to last <µs Page 9
