Hello Everyone,
I would like to ask you, if one of you can describe in detail reasons, why standard push-pull configuration of bipolar transistors is mostly used in common-emitter output configuration rather than common collector. Is there any reason for that ? I understand this configuration in pure analog design (class-B amplifier), but I don't understand this in motor control applications. Especially driving top NPN transistor, keeping Vbe on reasonable level with respect to various load seems to be tricky..
Many thanks for every hint.
Jiri
