WebJul 16, 2024 · 1. I'm having some trouble simulating a closed loop buck converter I designed.I am using PSIM for verifying the correctness of my circuit, but I can't figure out why the output is all wrong. It is supposed to be a 12 V to 5 V buck chopper at switching frequency = 200 kHz.Output power = 50 W.When a friend simulated a similar circuit on … WebJun 6, 2015 · Buck converter circuit when switch S is off (Mode-II) When the switch S is off, the KVL in Fig.5 gives, V L+ V O = 0 V L + V O = 0 ⇒V O = −L di dt. ⇒ V O = − L d i d t. As the output voltage is assumed constant by the small-ripple approximation, ⇒ L di dt = constant ⇒ L d i d t = c o n s t a n t ⇒ di dt = constant ⇒ d i d t = c o n s t a n t
