Problem 2: Pulse width modulation (PWM) is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts. The average value of voltage fed to the load is controlled by turning the switch between supply and load on and off at a fast rate. The longer the switch is on compared to the off periods, the higher the total power supplied to the load. PWM is particularly suited for running DC...

Problem 31: (34 points) 1. (10 points) A pulse width modulated (PWM) signal fPwM(t) in Figure 2. The symbol D represents a duty cycle, a number between zero and one. Determine the compact trigonometric Fourier series coefficients (Co Cn, θ.) of the signal f(t) 2. (10 points) One use of PWM is to generate variable DC voltages. While the PWM signal is not DC, you should be able to see from your results in part 1 that it has a...
P8.8 A forward converter supplied from a 25-V de source operates with the switch- ing frequency of 50 kHz and duty ratio of 0.5. The turn ratio of the trans- former is 1:1, the output capacitance is 150 uF, and the load draws a current of 2.5 A. Select the minimum inductance for continuous conduction mode and determine the average value and ripple amplitude of the output voltage.
