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: Ground mobile radar
Adjusting one of the VITA supply voltage outputs easily and quickly
Customer’s challenge
Recent battlefield experiences demand the rapid introduction of new protection systems for armored vehicles capable of detecting incoming threats: drones, micro-drone, projectiles and guide countermeasures. Time-to-market as well as a modern, open system architecture were essential to meet the market demands: the customer needed a VITA 62 compliant power supply but also customized outputs as well a quick development time and cost-effective NRE.
- Reduced time to market
- Customized outputs to meet specs
- Perform in the harsh conditions of battle
The Vicor solution
Vicor VPX solutions are time- and cost-efficient but also eliminate the need for re-engineering and trouble-shooting complex discrete component designs. In-depth tests verified system robustness in the demanding environment of modern armored vehicles. The supply was configured to provide the specific output required for radar main power supply, while maintaining VITA 62 compliance.
