Concept explainers

Single Phase Transformer

A single-phase transformer is a type of power transformer. It is an electrical device that accepts converts the single phase alternating power into single phase alternating power. In this power conversion the voltage is stepped up or down. If the voltage is stepped up, the current will be stepped down and if the voltage is stepped down, the current will be stepped up.

Question

A single-phase semi-converter is operated form 120 V, 50 Hz AC supply at a firing angle of 30 degrees.
The load is such that the load current is continuous and ripple-free. Displacement factor of the converter is:
(a) 0.77
(c) 0.67
(b) 0.97
(d) 0.57
