High-Efficiency DC-DC Power Supplies: Key Trends for 2025–2030

The global DC-DC power supply market is entering a growth phase, driven by accelerating investments in AI data centers, the widespread adoption of electric vehicles (EVs), and rapid advancements in industrial automation.

Based on WAWT’s latest comprehensive research on power supply market, the DC-DC market is expected to grow at a CAGR of more than 4.5%, with some application markets and regions growing much stronger than others.
This surge reflects the growing need for high-efficiency, high-density, and thermally optimized DC-DC modules that can support increasingly complex, power-intensive systems.

Data centers alone are expected to contribute of new DC-DC converter demand through 2030, propelled by AI workloads, 5G networks, and cloud computing. At the same time, the transition to 48V rack architectures and sophisticated Point-of-Load (POL) converters is reshaping the server power ecosystem. Meanwhile, the automotive sector is moving rapidly toward 800V EV platforms, generating strong demand for high-voltage isolated DC-DC converters used in onboard chargers, battery management systems, infotainment, and ADAS.

Industrial markets including robotics, AGVs/AMRs, factory automation, and renewable energy systems are also accelerating their reliance on rugged, compact, and efficient DC-DC power solutions. Between 2025 and 2030, the industry will see major innovation driven by wide-bandgap technologies (GaN & SiC), bidirectional DC-DC architectures, digital power management, and highly integrated power modules, defining the next era of power conversion.
