Solved Example on Step Up/Down Chopper
The output of a buck boost converter is 100V with input voltage 120V . If the frequency of the switch is 10KHz then the turn off time of the switch will be ?
Given output voltage = 100V
input voltage = 120V
Frequency f = 12KHz
For step up/down chopper = *
100 = *120
D = 0.45
= 0.45
T = = = 100 µs
Ton = 0.45 * 100
Ton =45 µs
Toff = T – Ton = 100 – 45
Toff =55 µs
