DC-DC Converter Using Negative-Output Feedback

Switched-capacitor (SC) DC-DC converters have several advantages over inductive DC-DC converters in that they are easily integrated on-chip and can scale to desired power levels, rendering themselves promising for integrated voltage regulators, especially for small, low-power systems. However, many SC DC-DC converters offer only a few conversion ratios, limiting their use for systems in which e...

Implementation of Floating Output Interleaved Input DC-DC Boost Converter

This paper presents the analysin ,design and implementation of a high voltage ratio topology of DC-DC converter. The DC-DC converter has high voltage ratio with reduced input current, output voltage and output current ripple, and also reduces the voltage and current rating of power electronics components and compared with conventional boost converter. The voltage stress on the switches are  red...

Single-Input Dual-Output (SIDO) Linear–Assisted DC/DC Converter

This article describes a single-input dual output (SIDO) linear-assisted DC/DC converter. Linear-assisted DC/DC converters are structures that allow to take advantages of the two classic alternatives in the design of power supply systems: voltage linear regulators and switching DC/DC converters. Thanks to the combination of a switching converter and two voltage linear regulators, the proposed S...

Zvzcs Pwm Dc-dc Converter with Controlled Output Rectifier

A new zero-voltage zero-current switching (ZVZCS) full-bridge phase-shifted PWM converter with controlled output rectifier is presented in this paper. Zero-voltage turn-on and zero-current turn-off for all power switches of the inverter is achieved for full load range from no-load to short circuit by using new secondary energy recovery clamp and modified PWM control strategy. Moreover by adding...
