How does a PWM duty cycle transform voltage?

Click For Summary
SUMMARY

The discussion focuses on the application of pulse width modulation (PWM) duty cycles in switched-mode power supplies (SMPS), particularly in boost converters. It highlights the role of PWM in voltage transformation, emphasizing how oscillation facilitates the step-up process. The user seeks additional resources and finds Wikipedia's article on SMPS to be a valuable starting point, providing numerous references for further exploration.

PREREQUISITES
  • Understanding of pulse width modulation (PWM) principles
  • Familiarity with switched-mode power supply (SMPS) concepts

I need to find out how a certain pulse width modulation duty cycle is used in SMPS power supplies (specifically a boost converter).

Also, how does the oscillation contribute to a voltage transformation? (step up)

Any pointers to some articles are welcome

Wikipedia's article is pretty useful, and they list lots of good reference pointers at the end:
