Base station wind power source load calculation

Wind Load Calculation Wind load is calculated using the following equation: Fw = 1 2 C V ⋅ ⋅ dp ⋅ ⋅ ⋅A ( ) ρ λ 2 Where: • Fw = Force due to wind (lbf, N) 3 3 • ρ = Air Density (.075lb/ft , 1.22 kg/m ) • Cdp = Profile Drag Coefficient (from text or experimental data) • λ = Length/Width Aspect Ratio Correction Factor • V = Wind Velocity (ft/s, m/s) • 2 2 A = Cross Sectional Area Normal to wind direction (length*width) (ft ,m ) 3 Table 1.

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.
