Chapter 2: summary of key points
Steady-state (DC) components of voltages and currents in a switching converter are obtained by averaging over a switching period
Complete steady-state solutionDC t f it lt d i d t t• DC components of capacitor voltages and inductor currents
• Inductor current and capacitor voltage ripples
Steady-state solution approach for any switching converterSteady-state solution approach for any switching converter• Small-ripple approximation greatly simplifies the analysis
• Inductor volt-second balance gives steady-state DC capacitor g y pvoltages
• Capacitor charge balance gives steady-state DC inductor currents
• Ripples can be found based on (approximately) constant slopes
ECEN5797
• Ripples can be found based on (approximately) constant slopes, (except in 2nd order filters)
