V = Ldi/dt, sudden change of current over time will induce voltage across inductor.... 所以inductor在dc-dc converter里是很常见的component... 如果你能控制charging/discharging time of inductor,你就能控制inductor voltage transfer to output storage capacitor...这就是我们所说的PWM driven dc-dc converter... 比如12V -> 3.3V buck converter。。 |
