''Six $$MOSFETS$$ connected in a bridge configuration (having no other power device) MUST be operated as Voltage Source Inverter $$(VSI)''.$$ This statement is
A
True, because being majority carrier devices. $$MOSFETS$$ are voltage driven
B
True, because $$MOSFETs$$ have inherently anti - parallel diodes
C
False, because it can be operated both as Current Source Inverter $$(CSI)$$ or a $$VSI$$
D
False, because $$MOSFETs$$ can be operated as execellent constant current sources in the saturation region
