In this article, a three winding coupled inductor-based dual active bridge (TWCI DAB) dc-dc converter is proposed. Similar to the current-fed DAB converter, proposed TWCI has small input current ripple and wide voltage range. addition, zero-voltage switching (ZVS) of all switches in full load range under variation can be realized. With magnetic integration structure, size total magnetics reduce...

This paper proposes a stand-alone photovoltaic (PV) system based on a DC-DC positive output super lift Luo (POSLL) converter. A conventional sliding mode control, a sliding mode controller using a simple sign function and a linear controller using proportional integrator (PI) are used for the control of the PV panel voltage and POSLL converter inductor current and these methods are compared tog...

Multicell converter are a very interesting alternative for medium and high power drives. This paper presents a new configuration of double flying capacitor (DFCM) converter. The main advantages of the proposed converter in comparison with FCM and stacked multicell converter are doubling the rms and the number of output voltage levels, improving the output voltage frequency spectrum, and cancell...

In this paper, a stochastic approach is proposed for reliability assessment of bidirectional DC-DC converters, including the fault-tolerant ones. This type of converters can be used in a smart DC grid, feeding DC loads such as home appliances and plug-in hybrid electric vehicles (PHEVs). The reliability of bidirectional DC-DC converters is of such an importance, due to the key role of the expec...

In this paper, a cardiac sense amplifier, i.e. the front end of a pacemaker, based on the Dynamic Translinear (DTL) circuit technique is presented. The system consists of a voltage-to-current converter, a bandpass filter, absolute value and RMS-DC converter circuits and an event detection circuit. From simulations, it is demonstrated that the DTL technique is a good alternative to conventional ...

This paper describes a DC isolated network which is fed with Distributed Generation (DG) from photovoltaic (PV) renewable sources for supplying unbalanced AC loads. The battery energy storage bank has been connected to the DC network via DC/DC converter to control the voltage of the network and optimize the operation of the PV generation units. The PV arrays are connected to the DC network ...

The present study attempted to design and evaluate a small portable electromyogram (EMG) amplifier that can output enhanced EMG and its root mean square (RMS) value. The production and design were of a laboratory scale without any special or high cost circuit construction. The designed amplifier was actually innovated according to the actual working conditions based on physiological anthropolog...

P&O embedded closed-loop control which simultaneously regulates DAB converter. ...

In this paper, a new structure for buck-boost Z-source converter based on Z-H topology is proposed. The proposed converter consists of two LC networks similar to the conventional Z-source and Z-H converters. One of the characteristics of the proposed structure is that, without any changing in its’ power circuit, it can be used in different conversions such as dc/dc, dc/ac and ac/ac. This unique...

Abstract – Resonant parametric perturbation (RPP) method is an effective non-feedback method for controlling chaos. In this paper, the above method is applied for the current programmed buck-boost dc-dc converter which exhibits chaotic for wide parameter variations. The different possible operating regimes leading to chaotic operation of the current mode controlled buck-boost converter is discu...
