优化 DC-DC 转换器稳定性：源阻抗效应的 AC 与瞬态仿真分析
探讨如何通过频域 AC 小信号分析和时域瞬态分析来优化 DC‑DC 转换器的稳定性
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.
