Q2) B) In a step-up converter, the duty ratio is adjusted to regulate the output voltage at 48V. The converter is supplied by a solar cell panel where its output voltage varies in a wide range as shown in the following V-I characteristics (Fig.PE-1). The maximum power output of the converter is 120 W. For stability reasons, it is required that the converter always operate in a CCM mode. The switching frequency is 50kHz. Assuming ideal components and C as very large, calculate the maximum value of L that can be used.

will give thumbs up! '1. Answer the ff: a. What is the output voltage (in V) of the op amp? b. What is the effective gain of this op amp circuit?
An op-amp with an open-loop gain of 6x105 and Vcc = 15 V has an output voltage of 3 Volts. If the inverting-input voltage is -1.8 microVolts then determine the non-inverting input voltage in microVolts to the single digit decimal place. Do not enter units. For example, if you calculate 3.1x10-6 Volts as your answer then enter 3.1. Similarly, if you calculate 1.872 x10-5 Volts as your answer then enter 18.7 (since this is 18.7 microvolts).
