Question

- Given that the duty cycle of a lossless boost converter changes following d =
0.002.sin(wt) + 0.3, t represents time and w represents angular frequency that
equals 2īt "fripple, fripple = 120 Hz, and output voltage V, is fixed at 100 V,
1. Please show the feasible range of input voltage Vin
2. For 20 s sts (20 s +3.T) (T, is the switching period and 1/T, = 10 kHz),
calculate and draw the equivalent duty cycle over the triangle carrier wave
and also draw the corresponding PWM signal. Summarize the results in a
scanned document or a Word document. T = 1/fs​

Answer 1

Explanation:

Draw the equivalent duty cycle (one sample point per switching period) WWW. 1 Draw the corresponding PWM signal to + T. to + 3T to + 2T, to = 20$ 1 CS Scanned with CamScanner
