<br />具体推导内容:While the transistor is ON Vx =Vin, and the OFF state the inductor current flows through the <br />diode giving Vx =Vo. For this analysis it is assumed that the inductor current always remains flowing <br />(continuous conduction). The voltage across the inductor is shown in Fig. 7(第二张波形图) and the average must be zero for <br />the average current to remain in steady state <br />由此得出公式: Vin*Ton + (Vin - Vo)*Toff = 0<br /><br />这个公式用到的是什么定理(电压和时间的乘积),不太明白,请DX们赐教这段推导过程，谢谢!<br /> |
