I am studying for my EE exam ,I understand the general working of the circuit but there is some details about it I have to know. this regulator supply 24 volt with puissance nominale 200watt. it consists of full bridge rectifier, power transistor T1 we control his pussance point by an error amplifier with gain 'k' ,transistor T2 amply current , we have also subtractor R1=3300 ohm and R2=1200 ohm. we assume that the minimum output voltage larger than Vout by 1 volt (ie 25 volt) I have to choose the Capacitos to achive a ratio of Triangular Oscillating about 30% around the average value of output voltage (Voltage drop on the transformer is about 5% from it's value when there is no load,and the diods Voltage drop is 0.6 volt).
how this circuit work? and what the voltage drop and the average voltage value and the power dissipation on the transistor T1
