WebThe buck converter uses an inherent switching action to regulate voltage. This switching frequency can affect the performance of a buck converter, and is thus very important. This application report analyzes the influence of switching frequency on buck converter performance in terms of efficiency, thermals, ripple, and transient response. WebExample: For a buck-boost circuit topology. V o = -20, V g =30. Find D and D’ in steady state. V V D D o g = − 1− ⇒ D V V V o o g = − D = − − = 20 50 0.4 and D’ = 0.6 Clearly D would vary with other PWD circuit DC - DC converter topologies even for the same V g and V o. If we further specified R L as 4Ω then Iout = 20V/4Ω = 5A ...
