Voltage-Mode Control当误差电压直接通过脉冲宽度调制器驱动占空比,这个被称为直接占空比控制或电压模式控制。电压模式控制中,误差电压与锯齿波相比较,得到占空比。 在电压模式控制下,如果出现过流或者短路故…
Ray Ridley 的“Current Mode or Voltage Mode” 电流模式的优点: 1. 易补偿 电压模式在滤波器谐振频率后相位急剧下降需要Type 3补偿器稳定系统。电流模式在低频象单极点系统,因为电流环控制了电感。这增加了相位裕量使变换器更易于控制。Type 2补偿器已足够了,极大地简化了设计。图1比较了电压模式和电流模式主...
Voltage-Mode, Current-Mode 电压模式电流模式.pdf,Technical Note TN-203 Sanjaya Maniktala, 2012 Voltage-Mode, Current-Mode (and Hysteretic Control) Introduction Switching regulators have been with us for many years. They were considered tricky to design –
Performance has been also compared for different supply voltage values. Thus design guidelines have been derived to select the most suitable topology for the... M Alioto,G Palumbo - 《IEEE Transactions on Very Large Scale Integration Systems》 被引量: 219发表: 2002年 Adaptive neural network contr...

Part Number: DP83869HM Hello Guys, Good day. Customer just wanted to clarify the outputs to the magnetics of DP83869HM, are they voltage driven or current mode
As you know each channel of DAC8775 can work at either current output mode or voltage output mode. And current and voltage output has separate pinouts. I am wondered can each channel of this device operate in current and voltage mode si...
講師先針對 Buck regulator topology 作簡單的介紹,接下來針對不同的control mode也有詳細的說明,最後再針對 TI 在 Notebook DC/DC 的相關產品進行說明。講師針對電源供應的理論與常見的筆電系統設計範例都有深入簡出的分析,是在進行筆電設計時相當實用的培訓影片。
The paper presents a PFC (Power Factor Correction) that uses Average Current-Mode control. The PFC strategy uses PI controller to correct the input current shape and a fuzzy controller to control the output voltage. Since the performance of fuzzy logic controller only depends on the selection of...
