MGVCL Exam Paper (30-07-2021 Shift 3)
A single phase full converter bridge, connected to 230 V, 50 Hz source is feeding a load R =10 Ω in series with a large inductance that makes the load current ripple free. For a firing angle of 450, calculate the rectification efficiency.
Due to the ever-increasing demand and growth in popularity of such advances as electric vehicles, there are several challenges power grid operators need to face. 1.Growing amount of renewable energy sources 2. Frequent power outages. 3. Increase in Energy Demand 4. Global rise in temperature 5. Grid modernization. 6. Electricity transmission losses.
