中文版,31页,描述Buck-boost变换器小节里面写道
图1-11中电流上升斜率每个周期均为Vin/L, 电流下降斜率为Vd/L。。。。。。
英文原版:
In Figure 1.11, the slope of the rising ramp is unchanged every cycle, being equal to VIN/L.The slope of the falling ramp is initially VD/L, where “VD” is the drop across the diode. Sofrom the inductor equation, initially ΔION . ΔIOFF. Thus, the current starts to staircase. Butthe magnitude of the slope of the falling ramp, and therefore ΔIOFF, keeps getting largerand larger as the capacitor charges up.
中文版会让初学者以为,每个下降阶段斜率都是Vd/L
英文版,是将rising 和 falling分开说。
rising是unchanged every cycle
falling是 initially VD/L
这个 initially 就能让人阅读过程中,注意到是初始化阶段。
