EV Bidirectional AC/DC Power Module Market - Global Forecast 2026-2032

The EV Bidirectional AC/DC Power Module Market size was estimated at USD 3.61 billion in 2025 and expected to reach USD 3.86 billion in 2026, at a CAGR of 6.88% to reach USD 5.75 billion by 2032.

The rapid acceleration of electric vehicle (EV) adoption has ushered in an era where energy flows bidirectionally between vehicles and the grid, demanding more sophisticated power electronics capable of both charging and exporting power. At the heart of this transformation lie bidirectional AC/DC power modules, engineered to seamlessly manage energy conversion with high efficiency and reliability. Such modules serve as critical enablers of vehicle-to-grid (V2G) and vehicle-to-home (V2H) applications, allowing parked EVs to stabilize the grid and reduce energy costs through intelligent power dispatch. Recent technological advancements have elevated these modules from niche prototypes to core infrastructure components in smart charging ecosystems.

Over the past two years, the landscape of bidirectional power modules has shifted dramatically, propelled by evolving policy frameworks and breakthroughs in semiconductor materials. Policymakers in the United States have enacted legislative measures that encourage V2G integration by mandating interconnection standards and compensation mechanisms for energy exported from EV batteries to the grid. Concurrently, pilot programs in Europe have demonstrated the viability of full-scale V2G deployments, such as those carried out by pioneering grid-tied power module manufacturers in France and the United States, revealing pathways to resilient charging infrastructures. These developments have catalyzed broader industry collaboration, forging alliances among automakers, utilities, and semiconductor suppliers to align technical standards, streamline certification processes, and accelerate commercial rollouts.

The introduction of new trade measures in 2024 and further updates in 2025 have reshaped cost structures for critical components like bidirectional AC/DC modules. Section 301 tariffs have elevated duties on Chinese-origin lithium-ion battery cells and related components from 7.5% to 25%, while Section 232 measures impose additional levies of 25% on automotive imports, cumulatively creating a cost burden approaching 55% for affected products. Meanwhile, retaliatory legal challenges culminated in a May 2025 ruling by the U.S. Court of International Trade, which invalidated certain broad-based tariffs under emergency powers, underscoring the uncertain regulatory climate and prompting manufacturers to reassess global supply chains. These overlapping tariff regimes have incentivized strategic sourcing shifts, including nearshoring of power module assembly and greater reliance on tariff-exempt supply channels under regional trade agreements.

Bidirectional AC/DC power modules cater to a diverse set of end users spanning commercial transport fleets that demand high-power charging systems, passenger vehicles that require compact onboard converters, and public transit networks seeking reliable depot-level charging infrastructure. Within these applications, the Charger segment bifurcates into offboard units favored by fleet operators for centralized energy management and onboard chargers embedded in vehicle architecture to enable mobile energy exchange. Moreover, DC-DC converters play a pivotal role in adapting battery voltage levels for auxiliary systems and grid interactions, while high-power inverters facilitate the conversion from direct current sources to alternating current loads. These modules are further differentiated by their power ratings, which range from compact designs under 50 kW for light-duty vehicles to robust systems exceeding 100 kW deployed in commercial and industrial contexts. Topological choices between isolated and non-isolated designs dictate the safety, size, and electromagnetic performance, while application scenarios span from stationary energy storage, where modules optimize renewables integration, to V2G, V2H, and vehicle-to-load use cases, each leveraging bidirectional energy flow to meet unique operational requirements.

Regional market dynamics for bidirectional power modules exhibit distinct characteristics across the Americas, Europe Middle East and Africa, and Asia Pacific. In the Americas, utility-backed pilot projects in California and New York, such as the collaboration between BorgWarner, Fermata Energy and Lion Electric on electric school bus V2G systems, have underscored the role of bidirectional hardware in grid resiliency and cost-reduction programs. Across Europe, Middle East, and Africa, the emergence of harmonized charging standards under industry consortia has facilitated large-scale deployments of modular power conversion systems in commercial fleets, while targeted incentives in Scandinavia and the Netherlands support residential V2H installations. Asia Pacific markets, led by government subsidies in Australia and pilot schemes aimed at leveraging EV batteries for home backup power, demonstrate the capacity for national programs to spur localized manufacturing and technology innovation, paving the way for integrated energy and mobility ecosystems.

The competitive ecosystem for bidirectional AC/DC power modules encompasses legacy power electronics leaders, automotive tier-one suppliers, and specialized innovators, each contributing unique strengths. Siemens, Delta Electronics, and ABB have leveraged decades of grid infrastructure expertise to develop high-efficiency bidirectional chargers now deployed in commercial vehicle fleets. Automotive component manufacturers such as Denso and Marelli have integrated power conversion units into next-generation EV platforms, aligning module form factors with stringent automotive safety and performance requirements. Semiconductor companies like STMicroelectronics have introduced SiC-based reference designs, such as the 7 kW STEVAL‐7BIDIRCB, demonstrating the scalability of wide-bandgap solutions for high-power applications. Meanwhile, gallium nitride-focused firms like Infineon have delivered compact multi-kW V2X systems with efficiency gains over 10%, underscoring the critical role of advanced materials in reducing module size, weight, and losses.

Industry leaders seeking to capitalize on bidirectional power module trends should prioritize modular and scalable architectures to support a broad spectrum of power ratings and topologies, ensuring rapid customization for diverse vehicle applications. It is advisable to establish strategic partnerships with semiconductor vendors to access next-generation GaN and SiC devices that deliver differentiated efficiency and thermal performance. Moreover, proactive engagement with regulatory bodies and standards organizations such as CharIN will enable companies to influence evolving interconnection and communication protocols, thereby reducing time-to-market for compliant solutions. Supply chain resilience can be fortified by diversifying manufacturing footprints across regions with favorable trade treaty provisions and by qualifying local content under regional agreements to mitigate tariff exposure. Finally, investing in integrated digital management platforms for charging and energy services will unlock new revenue streams from V2X applications while enhancing customer retention through value-added services.
