2: Assuming the PWM controller uses a reference voltage of 2.5V and a saw tooth generator has a peak to peak amplitude of 2V, design a PI controller as described in the lecture video such that the output voltage is regulated to 48V with a bandwidth that does not allow more than 3% THD. For the voltage sensor H(s), apply a low pass filter with a corner frequency of 1/10 the switching frequency to filter switching ripple
