Space Application DC-DC Converters

 
Below is a summary of the standard DC-DC and EPC design platforms for most satellite design applications. While these platforms meet most design applications, they are often modified and customized to meet customer’s specific electrical performances, system interfaces, operating environments, and unique mechanical form factors. While the converter assemblies feature mostly surface mount components on a PCB with and without an enclosure, International Rectifier also has unique design, fabrication and assembly expertise in space qualified thick film hybrid technology allowing the integration of a hybrid design minimizing material costs and miniaturization of an assembly’s form factor.
 

Space Level Design Platforms - Ratings and Features

ML Series – 5W, low power, dual output dc-dc converter for low noise amplifiers (LNA) and similar applications.

Mx Series – 5W and 15W low power triple output dc-dc converter for low noise amplifier (LNA), down converter (Do Con), transmitter, and receiver applications.

Ex Series - electronic power conditioners for solid state power amplifiers (SSPA) and high power amplifiers (HPA) requiring high efficiency performance, specific output sequencing for RF amplifiers. Two design patents are deployed enabling the world class efficiency performance.

Zx Series - low output voltage, high current DC-DC converters for digital signal processors, FPGA, ASIC, and other digital applications. Similarly to the E Series, two design patents are deployed enabling the world class efficiency performance.

SBB Series – 30W point of load (POL) class K hybrid voltage regulators.

Space Bourne Distributed Power Architecture (DPA) Solutions

A generic example of such DPA system is depicted below. The high efficiency Zx or GH series is ideal as the intermediate bus converter (IBC) converting a spacecraft’s unregulated or regulated bus voltage to an intermediate voltage of 5V. The SBB series point of load (POL) voltage regulator modules are used to provide the low supply voltages to the digital loads. The DPA power system offers many design benefits now that the newer digital devices require lower supply voltages and higher current. The benefits include reduced distribution losses, improved steady state and transient performance, optimum heat distribution, and smaller distribution cables and harnesses. Additionally, each POL can be optimized independently for their functions; future design upgrade can also be easily achieved with or without very minimum mechanical reconfiguration.

Quality Conformance Testing

Unlike standard commercial products, HiRel products must be submitted to various levels of quality conformance testing to ensure that the products are capable of performing to specifications in the often harsh environments of military and space applications. Both the United States and European community have each developed specifications that detail the sequence of quality conformance testing.

In the United States, the Defense Logistics Agency (DLA) is the controlling agency and has issued specifications that govern the quality conformance testing sequence performed on semiconductor devices and hybrid modules, namely MIL-PRF-19500/MIL-STD-750, MIL-PRF-38534/MIL-STD-883 and MIL-PRF-38535/MIL-STD-883.

MIL-PRF-38534/MIL-STD-883 are the controlling specifications for power hybrids. MIL-STD-883 directs hybrids te be manufactured to class H or class K.

International Rectifier HiRel Products Group manufactures and tests hermetic products to one of three distinct quality conformance levels: (1) commercial hermetic, (2) source control drawing (SCD), or (3) MIL-PRF-38534, MIL-PRF-38535 qualified. The HiRel Products Group also provides screened plastic encapsulated devices.

Glossary

Class H: Class H is the standard military quality level provided in MIL-PRF-38534, General Specification for Hybrid Microcircuits. It is intended for space applications.

Level B: Class level B defines the screening requirements for high reliability military applications as specified in MIL-STD-883 and is intended for use in class H products.

Level S: Class level S defines the screening requirements for high reliability space applications as specified in MIL-STD-883 and is intended for use in class K products.

JAN: JAN (Joint Army Navy) is the prefix assigned by the DSCC to designate devices on the DSCC qualified parts list.

JANTX: Military screening level as specified in MIL-PRF-19500 for a DSCC qualified device.

JANTXV: Military with visual inspection screening level as specified in MIL-PRF-19500 for a DSCC qualified device.

JANS: Space level screening as specified in MIL-PRF-19500 for a DSCC qualified device.
