Output Voltage Ripple Reduction in a Symmetric Multistage-Stacked Boost Architecture (MSBA) Converter

Simulation of Combined Boost Converter Behavior with Positive Output Voltage and Investigation of Voltage Ripple at Output

In this paper, the behavior of a hybrid back-boost converter with a positive output voltage is simulated. This converter consists of an amplifier voltage converter called KY converter and a modified synchronous converter (SR). The converter operates in continuous conduction mode (CCM) and has a non-shock output current, reducing the current stress in the output capacitor and reducing the output...

A New Transformerless Buck-Boost Converter With Positive Output Voltage

A new transformerless buck–boost converterwith simple structure is proposed in this study. Comparedwith the traditional buck–boost converter, the proposedbuck–boost converter’s voltage gain is squared times of theformer’s and its output voltage polarity is positive. Theseadvantages enable it to work in a wider range of positiveoutput. The two power switches of the proposed buck–boost converter ...

Bidirectional Buck-boost Converter with Variable Output Voltage

An increasing number of manufacturing processes rely on ultra-high speed and accuracy machines. Piezoceramic actuators are being utilized as parts of such machines. So far, only linear and switched-capacitor power supplies have been used for driving piezoceramic actuators in such applications. This paper proposes a switch-mode power supply to reduce cost and increase system efficiency. In the p...

A Control Scheme for an AC-DC Single-Stage Buck-Boost PFC Converter with Improved Output Ripple Reduction

Buck Supplies Output Voltage Ripple Reduction Using Fuzzy Control

Using the PWM control for switching power supplies the peaks EMI noise appear at the switching frequency and its harmonics. Using randomize or chaotic PWM control techniques in these systems the power spectrum is spread out in all frequencies band spectral emissions, but with a bigger ripple in the output voltage. The proposed nonlinear feedback control method, which induces chaos, is based by ...
