| Accurately predict loop gain in buck converters |
2008-03-01 |
| An accurate and fast approach to predicting the loop gain with different output power filters for the buck converter requires only two closed-loop measurements using a network analyser and a few algebraic calculations. Designers can then predict the loop gain for any output power filter by putting the inductor and capacitor parameters into one algebraic formula |
