A single phase full-wave half-controlled bridge converter feeds an inductive load. The two SCRs in the converter are connected to a common DC bus. The converter has to have a freewheeling diode |
| A. | because the converter inherently does not provide for free-wheeling |
| B. | because the converter does not provide for freewheeling for high values of triggering angles |
| C. | or else the free-wheeling action of the converter will cause shorting of the AC supply |
| D. | or else if a gate pulse to one of the SCRs is missed, it will subsequently cause a high load current in the other SCR |
| Answer» C. or else the free-wheeling action of the converter will cause shorting of the AC supply | |
