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: Electronic warfare suite for aircraft
A single 6U multiple power, high efficiency qualified to meet MIL-STD operational requirements
Customer’s challenge
Ensuring an aircraft’s survivability by integrating a wide-spectrum radar warning receiver and advanced self-protection jammers requires high power availability. The digital radio frequency, data acquisition and processing, and radar electronics are noise sensitive loads that require a solution with low EMI.
- Meet power needs of up to 1000W
- Fast time to market
- Meet MIL COTS standards and operational requirements for airborne platforms
The Vicor solution
The Vicor VITA 62 power supply provides superior density – 1000W in 6U form factor – and meets line and load regulation, output ripple and noise, and power sequencing to cater to the noise sensitive loads. Thermal seating planes are suitable for the advanced liquid cooling the customer required, and a VPX power supply would make it easier to replace or repair units.
