Bidirectional AC/DC Power Supplies
- Power supplies from 2kW up to 11kW
- Designed for ground mobile or industrial automation use
- Input/Output: 3AC input with active PFC
- Output/Input: High or low voltage DC
- High efficiency and power factor
RECOM’s bidirectional AC/DC power supplies are engineered for intelligent energy management, regenerative power, and advanced battery storage systems. By allowing energy to flow in both directions, these converters enable significant cost and space savings while increasing overall system efficiency. Whether you are developing EV infrastructure for intermediate energy storage or industrial recovery systems, RECOM provides the flexible, high-power architecture required for modern grid-tied applications.
Our platform-based designs utilize optimized topologies, such as CLLC and Phase-Shifted Full Bridge (PSFB), to ensure peak performance based on your specific conversion ratios. CLLC is ideal for applications where battery and PFC bus voltages are similar, while PSFB is the preferred alternative for substantial voltage gaps, such as 48V or 800V DC systems. RECOM’s modular approach allows us to modify these solutions quickly and cost-efficiently to meet unique industrial, transportation, and energy storage requirements.

Frequently Asked Questions
Bidirectional power supplies are essential for applications requiring two-way energy flow, such as battery charging/discharging, energy recovery systems, and energy storage (BESS). They are increasingly used in EV infrastructure to improve overall system efficiency and minimize energy loss through regenerative power.
Unlike conventional power supplies that only deliver power in one direction, bidirectional converters can both supply and absorb energy. This enables regenerative operation, battery balancing, and intelligent energy management in modern power systems.
Common bidirectional topologies include CLLC and phase-shifted full bridge (PSFB). The optimal topology depends on the relationship between battery voltage and the DC bus voltage, as well as overall system efficiency and application requirements.
Yes. Our platform-based designs are developed specifically for fast and cost-efficient modification. We can adapt voltage ranges, power levels, and mechanical formats to meet unique requirements in industrial, transportation, and energy storage sectors.
