“…The single-input and multiple-output (SIMO) dc-dc converters are commonly utilised in different kinds of applications including factory automation, stand-by power suppliers, and so on. SIMO dc-dc converters have been widely discussed [1][2][3][4][5][6][7][8]. Research has shown that cross-regulation is the most critical issue in SIMO converters [9].…”

Cross-regulation is one of the critical challenges in single-input and multi-output converters. In this study, new design guidelines and an analytical model for studying the cross-regulation between the dual-outputs of the fly-buck converter are proposed. A small-signal AC model is first established to obtain control over the output and to determine the cross-influence transfer functions of the system. Then, a load regulation coefficient and method for analysing the cross-regulation while considering the load magnitude and load change are proposed to study the characteristics of the fly-buck converter. Finally, to demonstrate the rationality behind the influencing factors over cross-regulation based on the resulting characteristics, a fly-buck converter with double control variables and lower cross-regulation is designed. Simulations and experimental prototypes are implemented to demonstrate the effectiveness of the proposed theoretical analysis.

A new non-isolated high-voltage gain three-port converter for standalone photovoltaic systems is proposed. The magnetic element of this converter is only one coupled inductor. The primary winding of the coupled inductor is shared between battery charger circuit and main converter. Leakage inductance energy of the coupled inductor is either transferred to battery or is regenerated via the passive-clamp circuit. Using switched capacitor and voltage lift techniques, the voltage gain is significantly increased for both low-voltage ports. Single magnetic element, high-voltage gain with reasonable duty cycle, lowvoltage stress on the switches, low winding turn ratio of coupled inductor and high efficiency are the merits of this converter. The operation principles and the steady-state analysis are described for the three modes of: single-input single-output, single-input dual-output and dual-input single-output. To verify the theoretical analysis, a laboratory prototype with 28 V input, 48 V battery voltage and 380 V output voltage is implemented and tested.

“…In [4], coupled inductors were employed to achieve a high voltage gain; however, the main and auxiliary switches operate under hard switching conditions, leading to higher switching losses and lower efficiency. A step-up converter proposed in [17] utilizes a snubber circuit comprising coupled inductors; this structure results in a ripple-free output current, but both switches are turned off under hard switching conditions.…”

A new auxiliary circuit for boost, buck, buck-boost, Cuk, SEPIC, and zeta converters is introduced to provide soft switching for pulse-width modulation converters. In the aforementioned family of DC-DC converters, the main and auxiliary switches turn on under zero current transition (ZCT) and turn off with zero voltage and current transition (ZVZCT). All diodes commutate under soft switching conditions. On the basis of the proposed converter family, the boost topology is analyzed, and its operating modes are presented. The validity of the theoretical analysis is justified by the experimental results of a 100W, 100 kHz prototype. The conducted electromagnetic emissions of the proposed boost converter are measured and found to be lower than those of another ZCT boost converter.
