This paper presents the maximum constant boost control method based on the space vector pulse-width modulation (SVPWM) technique for a three-phase Z-source inverter (ZSI). The advantage of the proposed control method is not only it retains the advantages of the carrier-based maximum constant boost control strategy but it also inherits good features from SVPWM technique. Compared with the carrier-based...
This paper introduces a set of positive output boost dc-dc converters applying the series voltage-lift technique. Compared with the traditional boost converter, the proposed circuits can perform positive-to-positive dc-dc voltage increasing conversion with higher voltage conversion ratios. They are different from other existing dc-dc step-up converters and are featured with the single-switch operation...
An introduction on the fundamentals of split-capacitors and -inductors is given in this paper. Positive output Luo-converter is taken as the platform by which the integration of split-capacitors/inductors with the voltage lift technique is implemented successfully. The voltage transfer gains of the newly-derived DC-DC topologies are significantly increased along with the number increasing of split-capacitors...
Voltage Lift Technique has been successfully employed in design of DC/DC converters, e.g. three series Luo-Converters. However, the output voltage increases in arithmetic progression. Super Lift Technique is the most significant contribution in Power Electronics, e.g. four series Super-Lift Converters. Their output voltage increases in geometric progression. This paper introduces a novel approach...
This letter introduces a new step-up dc-dc converter that provides a negative-to-positive voltage-conversion path for the negative dc-voltage source. Compared with the classical Cûk and buck-boost converters, the proposed converter increases the voltage boost ability significantly using the switched capacitor and self-lift techniques. It is featured with single power switch operation, common ground,...
Switched capacitor DC/DC converters are new prototype of DC/DC Conversion technology. Since switched capacitor can be integrated into a power IC chip, consequently, these converters have small size and high power density. Switched capacitor can be used in voltage-lift technique to construct DC/DC converters. The clue is that for the converters operating in discontinuous input current mode (DICM) the...
