2.1 电源电路(Power Circuit) PLECS演示模型库中的演示模型“同步降压转换器/Synchronous Buck Converter”中给出了同步降压转换器拓扑结构的描述。在该模型中,12V的输入电压在输出电压处逐步降低到5V。最初,有一个2.5Ω 存在电阻负载,但随后出现并联2.5Ω 负载接通,有效地将负载电阻减半。开关单元可以多相并联,这...
The self-driven synchronous buck converter circuit has the advantages that: a low-side drive chip is not required; and the follow current MOS field-effect transistor drive coils of the filter inductor L can assist in driving the follow current MOS field-effect transistor, so circuit is ...
