Electrical Engineering

  1. Derive the expressions of the average load voltage and currentin single-phase full-wave controlled rectifier (bridge rectifier)and resistive load. Draw the waveforms of supply voltage, outputvoltage, output current and thyristor current.   
  2. In a single-phase full-wave controlled rectifier (bridgerectifier) and resistive load, it is desired to get an average loadvoltage of 50 V. Determine the firing angle if the ac supplyvoltage is 150 V. If the average load power is 300W, calculate theaverage load current and. Design the thyristor.
  3. Derive the expressions of the average load voltage insingle-phase full-wave controlled rectifier (bridge rectifier) andhighly inductive load. Draw the waveforms of supply voltage, outputvoltage, output current and thyristor current.
  4. In a single-phase full-wave controlled rectifier (bridgerectifier) and resistive load, it is desired to get an average loadvoltage of 90 V. Determine the firing angle if the ac supplyvoltage is 230 V. If the average load power is 270 W, calculate theload current and. Design the thyristor.     Please solve all questions
