HOUSEHOLD ENERGY STORAGE POWER SUPPLIES

Common topologies of energy storage power supplies

Most popular topologies in this regard include the Dual Active Bridge with Extended Phase Shift (for example in TIDA-010054) which deals with a primary voltage of 700V to 800V DC, and secondary voltage of 350V to 500V DC (single-phase-shift SPS) or 250V to 500V (extended-phase-shift EPS) for power levels up to 10 kW, Phase-shifted Full-Bridge (for example in PMP22951) which deals with a voltage of 400V down to 54V and a power level of 3kW or CLLLC Dual-Active Bridge (for example in TIDM-02002) which deals with a primary voltage range of 380–600V to a secondary voltage range of 280–450V and power levels up to 6.6kW.
