A single-phase half-wave controlled rectifier has 400sin(314t) as the input voltage and R as the load. For the firing angle of 60 deg for the SCR, the average output voltage is
- A. 400/π
- B. 300/π
- C. 240/π
- D. 200/π
Answer: B. 300/π
Explanation: Average output voltage Vo = (Vm / 2π)(1 + cos α) = 300/π for the specified firing conditions.
