Paralleling Increased Power
4000B family modules connected directly parallel without additional components. This feature synchronous rectified type module. 4000B family converters utilizes proprietary synchronous rectifier drive technique that prevents modules from sinking current when connected parallel configuration. Furthermore, this unique drive allows module turn into established voltage (system voltage) without allowing output inductor current build negative direction. Finally, timing circuit been added disable synchronous rectifiers when module turned through on/off control.
Output Capacitance
When powering loads with significant dynamic current requirements, voltage regulation load improved addition decoupling capacitance load. most effective technique locate ceramic capacitors close load possible, using several capacitors lower effective ESR. These ceramic capacitors will handle short duration high frequency components dynamic current requirement. addition, higher values electrolytic capacitors should used handle mid-frequency components. equally important good design practices when configuring distribution system. resistance inductance (printed circuit board) layouts cabling should used. Remember that when using remote sensing, resistance, inductance capacitance distribution system within feedback loop power module. This have effect modules compensation resulting stability dynamic response performance. rule thumb, µF/A output current used without additional analysis. example, with (max 132W) power module, values decoupling capacitance 4000 used without regard stability. With larger values capacitance, load transient recovery time exceed specified value. much capacitance possible should outside remote sensing loop close load.The absolute maximum value output capacitance 10,000 values larger than this contact your local Ericsson representative.
Paralleling Redundancy
Even though 4000B family modules fully parallelable, modules were designed with current share function. Therefore, current sharing required, like 3902 added externally module. figure below shows redundant system with current sharing implemented. Diodes added output dc-dc modules allow failed module remove itself from system without causing failure system voltage. This configuration extended additional numbers power modules. DC-DC modules this configuration controlled individually groups means on/off control.
