In a fully controlled bridge converter feeding a resistive load the waveshapes of output voltage and output current

are always similar
can never be similar
may be similar or dissimilar
are similar only if a = 0

Correct Answer: are always similar

Explanation:

For resistive load output current is always proportional to output voltage.
