Analyze and design a boost converter

ourse Project Due: 5:00PM, April 10, 2015 (submit through Blackboard) Analyze and design a boost converter and its controller given the following specifications: An input voltage of 15V < Vin < 20V and an output of Vout = 40V over a load range of 1W < Pout < 100W. Switching frequency is fsw = 750kHz. 1) [5 points] Design the inductor (L) and capacitor (C). The current ripple ΔiL should be below 5% of the average inductor current IL at the maximum load. The steady state ripple ΔVout is below 0.5 % of the steady-state value of the output voltage. For the designed L, find the value of Iout,crit at the boundary of DCM and CCM. Plot Iout,crit vs. Vin. 2) [5 points] Analytically determine and draw the expected current and voltage waveforms for each component in your circuit at both light and heavy load. 3) [5 points] Using PSpice software, simulate the circuit under the heavy and light load conditions. Plot the voltage and current of each component over 3 switching intervals in the steady-state. Validate that the output of your simulation matches your analytical calculations in (2). 4) [7 points] Based on your designed circuit, calculate the transfer function
