Proximate Time-Optimal Digital Control for Synchronous Buck DC–DC Converters
This paper introduces an approach to near timeoptimal control for synchronous buck dc–dc converters. The proposed proximate time-optimal digital (PTOD) controller is a combination of a constant-frequency pulsewidth modulation (PWM) controller employing a linear PID compensator close to a reference point, and a linear or nonlinear switching surface controller (SSC) away from the reference, toget...
متن کاملAdaptive Nonlinear Control of Multiphase Synchronous Buck Power Converters
The problem of controlling multiphase synchronous buck power converters is considered. The aim is to regulate the output voltage of the converter and to ensure an adequate current sharing between its different channels. The control law is designed from the large-signal bilinear model (of the whole multichannels converter) using the backstepping technique. The obtained regulator is shown to meet...
متن کامل“Shoot-through” in Synchronous Buck Converters
The synchronous buck circuit is in widespread use to provide “point of use” high current, low voltage power for CPU’s, chipsets, peripherals etc. In the synchronous buck converter, the power stage has a “high-side” (Q1 below) MOSFET to charge the inductor, and a “Low-side” MOSFET which replaces a conventional buck regulator’s “catch diode” to provide a low-loss recirculation path for the induct...

متن کاملHybrid Control Method for Optimal Transient Response and Output Filter Minimization for Buck-Boost type Converters
This paper introduces a new digital control methodology for indirect energy transfer converters that is based on a hybrid controller concept. During transients, the control sets boundaries for inductor current and the output voltage based on the load conditions and the system requirements to facilitate rapid recovery and small output voltage variations. Once the output voltage is recovered, lin...
