An electronic assembly includes a first printed wiring board (PWB) on a first side of the electronic assembly, and a first stiffener secured to the first PWB. The electronic assembly also includes a second PWB on a second side of the electronic assembly, opposite the first side, a second stiffener secured to the second PWB, and a center stiffener seated in the second stiffener and between the first stiffener and the second stiffener. The center stiffener has a first side facing the first stiffener, a second side that is opposite the first side and facing the second stiffener, a first end, and a second end, opposite the first end. Electronic devices are secured to the center stiffener. The center stiffener dissipates heat from the electronic devices, and the electronic devices include power dies.

Conductive thermal management architecture for electronic devices

A cold plate includes a first side with a first surface, and a second side, opposite the first side. A coolant cavity is formed between the first side and the second side. A recessed base is machined into the first surface of the first side. The recessed base is bonded to a base copper plate and is a thinnest portion of the first surface.

Thermal management of electronic devices on a cold plate

A toroidal transformer assembly of an electronic component module assembly includes a transformer mounting plate receptive of the toroidal transformer. The transformer mounting plate includes a base, a center boss extending from the base, and an outer ring extending from the base, and spaced apart from the center boss. The center boss and the outer ring define a mounting location for a toroidal transformer therebetween. A plurality of fins are positioned to conduct thermal energy from the toroidal transformer to the base.

Thermal management of toroidal transformer mounted on a printed wiring board stiffener

A power converter may comprise a magnetic core, a transformer primary winding configured to generate a magnetic field in the magnetic core, and a transformer secondary winding matrix. The transformer secondary winding matrix may comprise a plurality of secondary windings configurable between various electrical connections relative to one another (e.g., in series or in parallel) to adjust a voltage conversion ratio of the power converter.

Multi-purpose power conversion module

An electrical power system may comprise a first energy source management converter (ESMC) configured to be connected in electronic communication with a first power source, a second ESMC configured to be connected in electronic communication with a second power source, and a multi-channel DC bus, wherein the first ESMC is configured to supply electric power to a first channel of the multi-channel DC bus, the second ESMC is configured to supply electric power to a second channel of the multi-channel DC bus, and the multi-channel DC bus is configured to supply electric power to a load.

Solar powered spacecraft power system

A power management and distribution system may comprise a first plurality of power sources, a first collector bus configured to receive power from the first plurality of power sources, an unregulated DC bus configured to receive power from the first collector bus, a regulated high voltage direct current (HVDC) bus configured to receive a first power from the unregulated DC bus, a first primary load bidirectional DC/DC converter configured to receive a second power from the unregulated DC bus, a first primary PDU configured to receive at least one of the first power from the regulated HVDC bus and the second power from the first primary load bidirectional DC/DC converter. The first primary PDU may be configured to supply power to a primary load such as a motor or actuator.

Power management and distribution architecture for a space vehicle

An electrical power system may comprise a first plurality of power sources, a first collector bus configured to receive power from the plurality of power sources, an unregulated DC bus configured to receive power from the first collector bus, a regulated high voltage direct current (HVDC) bus configured to receive power from the unregulated DC bus, and a first power distribution unit (PDU) configured to receive power from the regulated HVDC bus. The regulated HVDC bus may be configured to supply power to a high voltage load. The first plurality of power sources may comprise a first solar array, a first supercapacitor, and/or a first battery.

Electric power system for a space vehicle

An example solid state contactor assembly includes a switching element having a field-effect transistor and a diode in parallel. The switching element is configured to communicate electric current along a current flow path extending from a first bus bar to a second bus bar. A control device is configured to selectively communicate current along a portion of the current flow path through the field-effect transistor or the diode of the switching element.
