As electric vehicle charging infrastructure evolves toward higher power levels, bidirectional energy flow, and deeper integration with smart grid ecosystems, auxiliary power conversion has become a critical enabler of system reliability, safety, and communication integrity. RECOM Power is addressing these requirements with an expanded portfolio of high-efficiency AC/DC and DC/DC power conversion solutions specifically engineered for EV charging applications, including wallbox chargers, public fast-charging stations, and high-power DC charging hubs.

Modern EV charging systems operate across highly variable electrical environments, including three-phase industrial grids, single-phase residential supplies, and DC bus architectures in fast-charging networks. These systems are exposed to stringent electromagnetic compatibility (EMC) constraints, surge events, and overvoltage category III (OVC III) conditions, requiring robust isolation, reinforced insulation systems, and high transient immunity at the auxiliary power level.

RECOM’s power conversion architecture is built around compact, high-efficiency switching converter topologies designed to provide stable auxiliary supply rails for control electronics, gate drivers, communication modules, metering systems, and safety interlocks. The company’s AC/DC modules support wide input voltage ranges up to 528 VAC and are engineered for universal grid compatibility, enabling deployment across global charging infrastructure without redesign of the auxiliary power stage.

A key technological focus of RECOM’s platform is reinforced galvanic isolation. The converter systems incorporate high-isolation transformer designs and optimized creepage and clearance structures to ensure compliance with international safety standards while maintaining high power density. This enables reliable operation in harsh electrical environments where fast transient suppression and isolation integrity are critical for system protection and user safety.

RECOM’s switching power supply architectures leverage high-frequency conversion topologies to minimize conduction and switching losses while maintaining compact form factors suitable for space-constrained charging enclosures. The resulting reduction in thermal dissipation improves long-term reliability of downstream electronic subsystems, particularly in outdoor or thermally constrained installations.

RECOM’s product range spans low- to mid-power auxiliary supplies typically from 3 W to 60 W, optimized for distributed power architectures within EV chargers. These modules support high conversion efficiency, low no-load power consumption, and extended operating temperature ranges, typically from -40°C to +85°C, ensuring stable performance across diverse climatic conditions and duty cycles.

In addition to standardized converter platforms, RECOM offers application-specific power solutions tailored for advanced EV charging architectures, including bidirectional energy systems, smart charging controllers, and integrated power management units. These designs support emerging use cases such as vehicle-to-grid (V2G) interaction, dynamic load balancing, and intelligent charging orchestration.

The company also emphasizes EMC robustness and system-level noise immunity, ensuring compliance with stringent automotive and industrial electromagnetic standards. This is particularly critical in high-density charging installations where multiple power conversion stages operate in close proximity and switching noise coupling can impact system stability.

Through a modular and scalable design philosophy, RECOM enables system designers to implement flexible power architectures that support both centralized and distributed charging topologies. This approach reduces development complexity while improving system-level efficiency, reliability, and maintainability.

As EV charging networks continue to scale globally, demand is increasing for highly reliable auxiliary power systems capable of operating in electrically harsh and thermally demanding environments. RECOM Power’s solutions are positioned to support this transition by delivering compact, efficient, and safety-compliant power conversion platforms optimized for next-generation mobility infrastructure.
