Design a buck converter for the following specifications. Specifications: Input Voltage: 100 V Output voltage: 75 V Minimum output power: 250 W Maximum output power: 1500 W Switching frequency: 250 kHz Peak-to-peak inductor ripple current is 1A You may assume that the capacitances are large enough to be ignored in your design, i. e., the capacitor voltages will not change significantly over a single switching period. Your design should respond to disturbances as fast as possible.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
