EMI conduction interference increases shielding cost; unidirectional energy flow limiting ESS applications; communication gaps hindering smart management; grid fluctuations triggering false protection; low power density of traditional topologies increasing cabinet space costs. Our PFC power supply and power electronics innovations include:

• Proprietary Digital PFC Algorithm (3kW single-phase supports DC-AC bidirectional operation).
• Bridgeless Totem-Pole PFC (99% peak efficiency, IEC 61000-3-2 Class C compliant).
• 7kW 3-Phase Full-Bridge B6 Topology (efficiency >97.5%, integrated WiFi/RS485 communication).
• Vienna 3-Level Architecture (high power density design for 18kW inverters).
• Adaptive Dead-Time Control (switching loss reduced by 15%).
• Isolated Modbus Communication (EMC immunity > 4 kV).
• Triple Protection Mechanism (overcurrent/overtemperature/overvoltage shutdown)

Applications: 3-20 kW PFC power supplies, 2.5 kW bidirectional inverters, 18 kW industrial inverters, energy-storage systems; providing OTA upgrade interfaces for remote parameter optimization.
