A single phase semiconverter is feeding a highly inductive load and has freewheeling diode across the load. The waveshapes of output voltage and output current
Options
A. are similar
B. are not similar
C. may be similar or dissimilar
D. are similar only if firing angle is zero
Correct Answer
are not similar
Explanation
When freewheeling diode conducts output current exists but output voltage is zero.
