Archivio Istituzionale della RicercaThis article proposes the design, implementation, and simulation of a closed-loop voltage-mode controller for a grid adapter featuring an innovative, capacitive-isolated, Multi-Period Damped Resonant (MPDR) DC-DC converter. After presenting a mathematical model of the converter in open loop, different control strategies, i.e. frequency modulation (FM), Pulse-Width Modulation (PWM), Bang-bang control, and Dyadic Digital Pulse Modulation (DDPM), are introduced and analyzed. The four controllers are designed and compared in terms of dynamic performances by Simulink simulations. Preliminary experimental tests validate the converter operation on the four control strategies.

Abstract
This article proposes the design, implementation, and simulation of a closed-loop voltage-mode controller for a grid adapter featuring an innovative, capacitive-isolated, Multi-Period Damped Resonant (MPDR) DC-DC converter. After presenting a mathematical model of the converter in open loop, different control strategies, i.e. frequency modulation (FM), Pulse-Width Modulation (PWM), Bang-bang control, and Dyadic Digital Pulse Modulation (DDPM), are introduced and analyzed. The four controllers are designed and compared in terms of dynamic performances by Simulink simulations. Preliminary experimental tests validate the converter operation on the four control strategies.
