This paper introduces a closed-loop control architecture for an impedance control network (ICN) resonant dc-dc converter that regulates the converter's output voltage while achieving soft-switching across wide operating ranges. This architecture is based on enhanced phase-shift control of the ICN converter, in which the inverter and rectifier phase-shifts are simultaneously controlled to regulate...
This paper introduces an isolated step-down impedance control network (ICN) resonant dc-dc converter that utilizes enhanced inverter and rectifier phase-shifts to achieve both soft-switching and output voltage regulation. Compared to previously presented ICN converters, which utilize burst-mode control to achieve output voltage regulation, this ICN converter with the proposed enhanced phase-shift...
This paper introduces a new design methodology for high-frequency resonant dc-dc converters utilizing the recently proposed impedance control network (ICN) converter architecture. This design methodology guarantees zero voltage switching (ZVS) and near zero current switching (ZCS) of all transistors across the entire operating range of the converter. As compared to previous ICN converter design techniques,...
This paper presents an improved efficiency impedance control network (ICN) resonant dc-dc converter that maintains zero voltage switching (ZVS) and near zero current switching (ZCS) across wide ranges in input and output voltages and output power. The improvement in efficiency in this burst mode operated converter is achieved through an optimized startup control that minimizes its startup transient...
