TT Electronics’ Sanjeev Sachan, Engineering Director, explores how electrification is transforming modern defence systems.

In his article, Sanjeev outlines the global shift towards battery-powered, hybrid‑electric, and high-voltage architectures across land, sea and air platforms. Electrified systems can reduce reliance on diesel, lower logistical burdens, operate more quietly, and offer flexible power distribution for mission-critical applications.

The article also explores key engineering challenges. Thermal management remains critical — controlling heat in high-power conversion systems without compromising weight or reliability is a major focus. Designers must also balance power density, electromagnetic compatibility, and stealth requirements, while ensuring robustness for demanding military environments.

From an architectural standpoint, modern electric military systems rely on a layered approach: energy storage, power conversion and conditioning, and load interfaces for motors, mission electronics, or other subsystems. The adoption of wide-bandgap semiconductors (SiC and GaN), ruggedised magnetics, and advanced interconnects is enabling higher efficiency and more compact designs suitable for defence applications.

TT Electronics’ strength lies in our vertical integration across the power chain — from discrete magnetics and power modules to high-voltage converters and line-replaceable units. This systems-level capability allows optimisation of designs for real-world usage, delivering right-sized solutions aligned with actual mission requirements. Sanjeev also highlights the importance of early integration of reliability prediction, component selection, and architectural decisions to ensure long-term performance across the platform’s life.
