A single-phase full-bridge voltage-source inverter feels a purely inductive load, as shown where T1, T2, T3, T4 are power transistors and D1, D2, D3, D4 are feedback diodes.
The inverter is operated in square-wave mode with a frequency of 50 Hz.
If the average load current is zero, what is the time duration of conduction of each feedback diode in a cycle?
A. 5 msec
B. 10 msec
C. 20 msec
D. 2.5 msec
