In solar PV dcdc conversion and fuel cell dcdc conversion, the input voltagte is low (e.g. 40V - 50V) and the output voltage is pretty high (e.g. 300V-400V).  The best topology for the power conversion is boost mode current fed converter. ADP1055 is the best candicate for this type of application:

1. ADP1055 offers fast control loop and high PWM resolution.

2. ADP1055 offer extra pole or zero, which can be used to cancel out the Right Half Plane Zero (RHPZ) of the boost converter.
