a collocate-AB effectiveness amplifier is to be purposed control a 6.0W, 12 load. Darlington effectiveness transistors with =1250 and rated at 19W control =150 C, are profitable. A diode prepossessioning network with diodes of joining greatness 1/20 that of the effectiveness transistors is to be used to bestow collocate AB influence.
a) What is the optimum and <(max)>?
b) if we exact that the currect through the diodes deviate by no over than a ingredient of 6, what (ordinary fountain) is essential and what results?
c) Suppose that the singly effectiveness accoutre profitable has Vs = ±15V. VL(Max) does referable substitute, and neither does the Iprepossession exactment. But VL(worst), PD(worst, collocateB) , and PDQ do. What are their values?
D) What is (worst,total)?
e) What greatness excitement sinks are needed control each transistor if we exact a prophylactic margin = 25 C
