Modeling and Design of Digitially Controlled Voltage Regulator Modules
… a high resolution Digital Pulse-Width-Modulator (DPWM). However, designing such a DPWM which can meet the requirements of VRMs application requires ultra-high system clock frequency, up to several GHz. Such high frequency is impractical due to huge power consumption. Hybrid DPWM might be an …

Optimal nonlinear digital signal processing : a dynamical systems approach
… of digitally implemented pulse-width modulators (DPWM) used as quantizers for power amplifiers in switched-mode operation. A time-domain input-output model of DPWM which offers new insight into nonlinear behavior of this system is developed. A modified Lloyd-Max quantization based algorithm for …

Modeling and design of digital current-mode constant on-time control
… by the quantization effect from the ADC and DPWM of the digital control chip. Another issue is the delay problem coming from the sample-hold effect. In this thesis, the modeling, analysis and design methodology for the constant frequency voltage-mode control is reviewed. A DPWM (Digital Pulse …

Analysis and Design of Paralleled Three-Phase Voltage Source Converters with Interleaving
… VSCs with discontinuous space-vector modulation (DPWM) and interleaving are proposed. With the control methods, DPWM and interleaving, which is a desirable combination, but not considered possible, can be implemented together. In addition, the total flux of integrated inter-phase inductor to limit …

Current source based wind energy conversion system
… width modulated current source converter (BTB-DPWM-CSC) as an interface for a dual three-phase PMSG, with two stator windings, shifted by 30°. Both the generator and grid side dual PWM rectifier and inverters (CSR and CSI) of the WECS are controlled using selective harmonic elimination (SHE) …

Current-Mode Control: Modeling and its Digital Application
… High-resolution digital pulse-width modulator (DPWM) is considered to be indispensable for minimizing the possibility of unpredicted limit-cycle oscillations, but results in high cost, especially in the application of voltage regulators for microprocessors. In order to solve this issue, a fully …

45nm direct battery DC-DC converter for mobile applications
… are used. A new digital pulse width modulator (DPWM) architecture is presented which provides 75% area savings over the conventional delay line and counter based architecture with comparable power consumption. The buck converter also requires Switched Capacitor (SC) DC-DC Converters to generate …
