Abstract: There is disclosed an enclosure and cooling system for electronic equipment that provides forced-air cooling of multiple compartmentalized electronics assemblies while simultaneously isolating the electronics assemblies from the ambient environment, keeping the electronics assemblies free from contamination due to harmful dust, dirt, water, corrosives, and other airborne foreign matter. Embodiments include an air-conduction cooled environmentally-sealed electronics enclosure having at least first and second environmentally-sealed electronics compartments, each containing a respective electronic assembly. A common-air cooling channel containing a fin core is disposed between the first and the second electronics compartments, such that ambient air drawn from an air intake, through the common channel, and out an air exhaust removes heat generated by the electronic assemblies within the sealed compartments to an exterior of the enclosure. Other embodiments are disclosed.

Abstract: A drive circuit arranged to drive a synchronous rectifier of a power converter includes a differential amplifier stage connected to the synchronous rectifier and arranged to supply a drive signal to the synchronous rectifier to turn the synchronous rectifier on and off and a high voltage blocking stage connected between the synchronous rectifier and the differential amplifier stage. The differential amplifier stage is arranged such that a voltage level of the drive signal depends on a load of the power converter.

Abstract: A method for determining a fan speed for a fan used to cool a payload is disclosed. The method includes, according to various embodiments, receiving a first signal indicative of a first fan speed and receiving a second signal indicative of a system temperature. The method further includes selecting a temperature setpoint based on the first fan speed and, based on a comparison of the system temperature and the selected temperature setpoint, computing a first fan speed output. A thermal management system and method for determining a speed-setpoint droop characteristic are also disclosed.
