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.
