Optimizing DC-DC converter stability: AC and transient analysis in simulations of source impedance effects
Learn how to optimize DC-DC converter stability through AC analysis in the frequency-domain and transient analysis in the time-domain
Case study: Enhanced missile defense
Efficiently powering the growing suite of advanced on-board sensors
Customer’s challenge
As missile defense weapons become more sophisticated, they require higher performance power delivery to successfully incorporate advanced on-board technology to ensure more accurate and successful performance. Key goals were:
- 28V MIL-STD-704F input conversion to –28V
- Delivery high power in difficult circumstances
- Provide the necessary performance to enhance mission success
The Vicor solution
Vicor high-performance power modules provided the thermal, mechanical, and density benefits necessary to power the advanced onboard functionality. Powering an isolated, regulated –28V bus, the Vicor DCM3623 provides the DC-DC conversion with a wide input range of 16V to 50V, and peak efficiency of 93.6% with superior power density.

Power delivery network
A 28V MIL-STD-704F input to -28V at 300W is converted using a DCMTM isolated, regulated
DC converter. The thermal, mechanical and density benefits of Vicor ChiP packaging allow for
cost-effective power solutions with previously unattainable system size and weight. Coupled
with the high efficiency gained through zero voltage switching (ZVS) topology, these
modules provide superior power system performance in a wide variety of environments. In
this application, the Vicor DCM3623 provides DC-DC conversion with a wide input range of
16V to 50V, peak efficiency of 93.6% and power density of 818W/in3.
