The model should include: 1. A PV solar panel as the input power source. 2. A Boost Converter circuit for voltage regulation. 3. A battery charging system. 4. Simulation results showing voltage, current, and efficiency of the system. Please provide the Simulink file and any necessary explanations.arrow_forwardQ1. A 450 V, 50 Hz, 1450 r.p.m., 25 kW, star-connected three-phase induction motor delivers constant (rated) torque at all speeds. The motor equivalent circuit parameters at rated frequency are R1=0.12, R2 = 0.17 2, X₁ = 0.3 2, X2 = 0.5 2, Xm = 23.6 2. Smooth speed variation is obtained by primary frequency control with simultaneous variation of the terminal voltage to maintain constant air-gap flux.
