An active-clamped, zero-voltage switched forward converter equipped with a soft-switched synchronous rectifier is designed and implemented for some low output voltage applications where maximized efficiency is of utmost importance. The converter efficiency is maximized due to soft-switching of the main, active clamp and the synchronous rectifier MOSFET switches. Experimental results are presented for a converter with a de input voltage of 48V, an output voltage of 5V and a de electronic load up to 10A. The measured efficiency was 92% for an output power of 50 W.

Highly Integrated 3 V Supply Electronics for Electromagnetic Energy Harvesters With Minimum 0.4 V-peak Input Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2017-07-01) This paper presents a self-powered interface enabling battery-like operation with a regulated 3 V output from ac signals as low as 0.4 V-peak, generated by electromagnetic energy harvesters under low frequency vibrations. As the first stage of the 180 nm standard CMOS circuit, harvested signal is rectified through an ac/dc doubler with active diodes powered internally by a passive ac/dc quadrupler. The voltage is boosted in the second stage through a low voltage charge pump stimulated by an on-chip ring osc...
Active clamped ZVS forward converter with soft-switched synchronous rectifier for high efficiency, low output voltage applications Acik, A; Cadirci, I (Institution of Engineering and Technology (IET), 2003-03-01) The analysis, design, and implementation of an active clamped ZVS forward converter equipped with a soft-switched synchronous rectifier (ACFC-SR), proposed for high-efficiency low output voltage DC-DC converter applications, is presented. The converter efficiency is maximised due to soft switching of the main, active clamp, synchronous rectifier, and freewheeling MOSFET switches. The operating principles of the ACFC-SR are analysed in detail, and the converter performance is compared with that of alternativ...
Design and implementation of a voltage source converter based statcom for reactive power compensation and harmonic filtering Çetin, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007) In this thesis, design and implementation of a distribution-type, voltage source converter (VSC) based static synchronous compensator (D-STATCOM) having the simplest converter and coupling transformer topologies have been carried out. The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
Output voltage control of a four-leg inverter based three-phase ups by means of stationary frame resonant filter banks Demirkutlu, Eyyüp; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2006) A method for high performance output voltage control of a four-leg inverter based three-phase transformerless UPS is proposed. Voltage control loop is employed and the method employs stationary frame resonant filter controllers for the fundamental and harmonic frequency components. A capacitor current feedback loop provides active damping and enhances the output voltage dynamic performance. The controller design and implementation details are given. Linear and nonlinear loads for balanced and unbalanced loa...
Operating principles and practical design aspects of all SiC DC/AC/DC converter for MPPT in grid-connected PV supplies ÖZTÜRK, SERKAN; Popos, Polat; Utalay, Volkan; Koc, Atila; Ermiş, Muammer; ÇADIRCI, IŞIK (2018-12-01) A 20 kW, 20 kHz high frequency (HF) link maximum power point tracking (MPPT) converter for a grid-connected PV supply, based on all silicon carbide (SiC) power semiconductors, is presented. In the developed converter, SiC power MOSFETs are used in the low-voltage PV panel side and SiC Schottky diodes on the high-voltage DC output, in order to maximize the power conversion efficiency and the power density. Operating principles of the resulting dual H-bridge MPPT converter and the practical aspects of the con...
