A full bridge DC-DC converter supplies a pure resistive load
using bipolar PWM voltage switching at 10kHz with vcontrol =
0.75Vtri. If Vd = 50V and io = 2A:
a. Draw the output voltage (uo (t)) and the output current (io
(t)). Identify the components as leader (TA +, TA-, DA +, DA-, TB
+, TB-, DB + and DB-) for different time intervals. including
numerical values on both axes.
b. Calculate the DC output voltage (Vo), the DC input current (Id)
and the maximum load current (Io, max).
c. Using Fourier analysis, calculate the amplitude of the switching
frequency harmonic components of the output voltage uo.
