The Research of Three-phase Boost/Buck-boost DC-AC Inverter

This paper presents a new inverter based on three-phase Boost/Buck-boost single-stage inverter. The basic configuration of the new topology and their fundamental principle are firstly introduced, the method of design double-loop controller and sliding mode controller are clarified, analyzed and compared in the following. Finally the validity and feasibility of the new topology are tested by sim...

Sliding Mode Control of a Bidirectional Buck/Boost DC-DC Converter with Constant Switching Frequency

In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...

DC/DC Boost-Boost power converter as a didactic system: Experimental results with Matlab/Simulink via current and voltage probes

Input Voltage and Current Sensorless Control of a Single Phase AC-DC Boost Converter

It is well known that measuring the input voltage and current, as the feedforward and feedback terms, are vital for the controller design in the problem of power factor compensation (PFC) of an AC-DC boost converter. Traditional adaptive scenarios corresponds to the simultaneous estimation of these variables are failed because the system dynamics is not in the classical adaptive form. In this p...

A Soft Switching Dc-dc Boost Converter with Passive Snubber

This paper introduces a new soft switching boost converter with passive snubber. In the proposed converter, the main switch turns on under zero current switching (ZCS) and turns off under zero voltage switching (ZVS) without any additional voltage or current stresses. The main diode turns on under ZVS and turns off under ZCS. The proposed converter has features as low cost, simple control, low ...
