Overview
Our series of bidirectional AC↔DC chargers is designed to meet the rapidly growing demand for flexible, efficient, and grid-aware charging solutions. Offered in 2.2 kW, 3.8 kW, and 6.6 kW variants, these chargers operate seamlessly with 48V and 400V lithium-ion battery systems. Their bidirectional capability allows them to not only charge from the grid (G2V) but also return power back to the grid or local loads (V2G) — enabling true smart grid integration.
Typical Clients
- EV OEMs integrating auxiliary or onboard charging modules.
- Battery energy storage providers needing modular charging platforms.
- Renewable and microgrid developers seeking intelligent charge/discharge units.
Use Cases
- Residential or commercial battery energy storage charging.
- Onboard EV auxiliary chargers for passenger or light commercial vehicles.
- Microgrid stabilization, demand-response, and backup power.
Design Philosophy
- Built on wide-bandgap devices (SiC and GaN) to reduce losses and improve switching frequency.
- Totem-Pole PFC for high-efficiency AC input stages.
- DAB or LLC resonant stages for compact, efficient DC conversion.
- Designed with compliance baked in — IEC 61851, IEEE 1547, CISPR EMI standards.
- Modular design ensures easy adaptation for higher or lower power ratings.
