question

(1) A 1.5-kw single-phase converter operates at full load from a 230-volt a-c source. Neglecting losses, and assuming a power factor of unity, calculate: (a) the d-c voltage and current; (b) the a-c input current. (2) A 2.5-kw single-phase converter is operated inverted, i.e., it converts direct to alternating current. If the d-c input voltage is 230, calculate: (a) the a-c voltage; (b) the alternating and direct currents at full load.
