VPT High-Reliability Power Conversion Products for Aerospace Programmes

VPT - Lead

VPT is a leading supplier of power conversion solutions for critical power systems in aerospace applications such as launch vehicles and deepspace facilities.

The company provides reliable and highly efficient direct-current-to-direct-current (DC-DC) converters, electromagnetic interference filters (EMI), and other power accessories that conform to MIL-PRF-38534 Class H and Class K standards.

Remote and non-isolated DC-DC converters for aerospace projects

VPT’s remote and non-isolated synchronous, buck-regulated point-of-load DC-DC converters and EMI filters decrease the weight, heat, and cost of electronic board space.

Ranging from 6W-120W output options, the VPT SV and SVR Series offer radiation- tolerant and radiation-hardened products with varying levels of total ionising dose (TID) and single event effects (SEE) performance to suit several programme needs.

Cost-effective power converters for space operations

VPT provides two series of regular DC-DC converters and accessories that have been created and tested to operate in complex aerospace environments.

The isolated converters can be combined with the company’s non-isolated point of load converters and EMI filters to create a lightweight and highly cost-effective power system suitable for space applications.

Defense Logistics Agency-approved aerospace power converters

The SVR Series has a TID performance of 100 krad(Si) and SEE of 85MeV-cm²/mg.

The series complies with the technical operating report (TOR) requirements and conforms to MIL-PRF-38534 Class K that has been set out by the Defense Logistics Agency (DLA) for Standard Microcircuit Drawings (SMD).

SVR DC-DC converters also include a DLA-approved radiation hardness assurance (RHA) plan.

VPT’s SV Series allows a 30 krad(Si) TID and a SEE of 44 MeV-cm²/mg. They are certified to MIL-PRF-38534 Class K by the DLA SMDs and have an RHA plan approved by the DLA.

Both series have a 28VIN and have standard industry output voltages. The DC-DC converters provide full performance across temperature ranges of -55°C-125°C.

The converters’ components are selected from NASA’s database of recommended radiation-hardened devices. They have fault-tolerant magnetic feedback circuits with multiple protection features and no optocouplers.

VPT’s converter components receive radiation lot acceptance testing (RLAT) at both high-dose rate (HDR) and extremely low-dose rate sensitivity (ELDRS).

Immediate delivery of power conversion systems

VPT understands project targets and the need for a quick turnaround. This is why the company maintains industry-leading stock levels, which allow for immediate delivery in almost all cases.

Leading customers around the world depend on VPT for innovative technology, fast product delivery, and certified quality.
