    The rectification efficiency of a single phase Half Wave Controlled R...
    The rectification efficiency of a single-phase half-wave controlled rectifier can be calculated using the following formula:

    η = (Vdc / Vac) × 100

    Where:
    η is the rectification efficiency
    Vdc is the DC output voltage
    Vac is the AC input voltage

    In a half-wave controlled rectifier, the output voltage is given by the equation:

    Vdc = (2 / π) * Vac * (1 - cos(α))

    Where:
    α is the delay angle

    To calculate the rectification efficiency, we need to substitute the values into the equations and solve for η.

    Given:
    Delay angle (α) = π/2

    1. Calculate the DC output voltage (Vdc):
    Vdc = (2 / π) * Vac * (1 - cos(π/2))
    = (2 / π) * Vac * (1 - 0)
    = (2 / π) * Vac

    2. Calculate the rectification efficiency (η):
    η = (Vdc / Vac) × 100
    = [(2 / π) * Vac / Vac] × 100
    = (2 / π) × 100
    ≈ 20.23%

    Therefore, the rectification efficiency of the single-phase half-wave controlled rectifier with a resistive load and a delay angle of π/2 is approximately 20.23%.

    Note: The rectification efficiency represents the percentage of AC power converted into DC power. In this case, since we are using a half-wave rectifier, only half of the AC input waveform is utilized, resulting in a lower rectification efficiency compared to full-wave rectifiers. The delay angle determines the point in the AC cycle at which the rectifier starts conducting, and a delay angle of π/2 means the rectifier conducts from the peak of the AC waveform.
