“…3(a)(c)(e)(g), in this case closing switch s b would connect the floating capacitor in parallel with the dc-source. Similarly, when the first and last digits are both one, the positive side of the capacitor is connected to That is the way the capacitor can be charged in several switching states, a resonant inductor may be added in series with s a and s b to limit the peak current in the capacitor charging path if necessary, for example as in [5].…”

This paper presents a cascaded-type multilevel inverter whit only one DC voltage source, which uses a floating capacitor to feed the other cascaded H-bridge, the capacitor is charge in a bootstrap technique and then the converter can provide a peak voltage equal to twice the DC-source regard-less on the power factor in the load, the converter is ideal for renewable systems applications as inverter stage in energy generation or grid integration, experimental results with a 5-level prototype verify the converter behavior.

“…Plenty of high voltage gain topologies has been introduced (Luo and Ye, 2003;Wu et al, 2005;Jang and Jovanovic, 2007;Axelrod et al, 2008;Ismail et al, 2008a;Wu et al, 2008;Fardoun and Ismail, 2010;Choi et al, 2011;Jiao et al, 2011;Luo, 2011;Qian et al, 2012;Rosas-Caro et al, 2013;Li et al, 2015;Yang et al, 2009). Although control engineering has considerable progress over recent decades, most applications use PID controllers, because of their low price and simplicity.…”

Environmental friendly energy sources like solar, fuel or wind cells provide low voltage levels. Grids work with higher voltage levels so step up is required before connecting these new energy sources to grid. Conventional boost converter is not able to provide a large DC gain. There are some topologies available in literature which provides required high DC gain. Without a suitable control system, converter's output may change due to disturbances like: Input voltage's changes and output load's changes. This paper designs a controller for one of the recently proposed high DC gain topologies. Converters dynamical equations are extracted using State Space Averaging (SSA). Controller is designed based on the obtained dynamics.Close loop system has been tested in Simulink ® environment. Simulation results showed the performance of designed controller.

“…Therefore, it is necessary to limit the input current ripple through proper equipment or a control method [4][5][6][7][8]. An additional hardware filter can be installed to limit the highfrequency input current ripple on the basis of the switching frequency.…”

“…Several topologies without a filter have been proposed to reduce the input current ripple [4][5][6][7][8]. Reference [5] proposes double-Cúk with a coupled inductor, and it achieves a near-zero input current ripple.…”

“…However, its double-stage configuration and the added passive components may decrease its efficiency and power density. The studies in [6][7][8] employ capacitors and inductors for ripple cancellation, and thus, these topologies also need additional components. Moreover, the operation mode of [7][8] is continuous conduction mode (CCM), which results in switching noise with steep dv/dt and di/dt due to the reverse recovery current of the diode [9].…”

-In this paper, a discontinuous conduction mode (DCM) frequency control algorithm is proposed to reduce the input current ripple of a multi-phase interleaved boost converter. Unlike conventional variable duty and constant frequency control, the proposed algorithm controls the switching frequency to regulate the output voltage. By fixing the duty ratio at 1/N in the N-phase interleaved boost converter, the input current ripple can be minimized by ripple cancellation. Furthermore, the negative effects of the diode reverse recovery current are eliminated because of the DCM characteristic. A frequency controller is designed to employ the proposed algorithm considering the magnetic permeability change. The proposed algorithm is analyzed in the frequency domain and verified by a 600 W three-phase boost converter prototype that achieved 57% ripple current reduction.
