The sensorless vector control method in induction motor drives is utilized more and more popular in industry applications. The traditional current loop controller is PI regulator but its bandwidth is limited by switching frequency. In this paper a predictive current controller is proposed to solve the limitation of bandwidth in ...
WebThe switching regulator operates at high frequency, typically above 1 MHz, allowing the use of small external components. In worst-case scenarios, it must power dynamic loads, so the feedback resistor network must provide enough bandwidth to … WebJan 20, 2015 · For example, a current-mode control regulator responds to line- or load-voltage changes much more quickly than voltage-mode, it eliminates the loop gain variation with input voltage drawback of voltage-mode, compensation is easier to implement, and the circuit also exhibits a higher gain bandwidth compared to voltage-mode.
WebCurrent-mode converters typically have a blanking time, which sets the minimum D for a given Vout, and therefore max VIN, that will be regulated without reducing switching frequency (pulse skipping).
