Boost power converters have been widely used for Power Factor Correction (PFC) in AC-DC conversions [1] and for power management in battery powered DC-DC conversions [2]. Moving beyond low-power applications, such as cellular phones, smart phones and other portable electronic products, boost converters are being used more and more in medium-power applications. For example, in computing and cons...

This paper proposes a new solar power generation system, which is composed of a DC/DC power converter and a new seven-level inverter. The DC/DC power converter integrates a DC-DC boost converter and a transformer to convert the output voltage of the solar cell array into two independent voltage sources with multiple relationships. This new seven-level inverter is configured using a capacitor se...

an automatic fuzzy control (AFC) system for a parallel dc-dc converter, and the control objective is to achieve the stable voltage regulation and uniform current distribution. The average model for an example of a three-module boost converter, which is composed of three conventional boost converter frames in parallel connection, is derived for the design of this AFC system including voltage and...

Photovoltaic (PV) systems with a battery back-up form an integral part of distributed generation systems and therefore have recently attracted a lot of interest. In this paper, we consider a system of charging a battery from a PV panel through a current mode controlled boost dc-dc converter. We analyze its complete nonlinear/nonsmooth dynamics, using a piecewise model of the converter and reali...

This paper presents an analysis of coupled inductor for interleaved boost converter and the effect of coupled inductor on current ripple reduction and on load transient response time. From the analysis a ETD core based coupled inductor structure is proposed to maximize the performance of the DC-DC converter. The inductor can be designed in convenient way by using commercially manufactured coil ...

Within the photovoltaic (PV) power-generation market, the ac PV module has shown obvious growth. However, a high voltage gain converter is essential for the module’s grid connection through a dc–ac inverter. This paper proposes a converter that employs a floating active switch to isolate energy from the PV panel when the ac module is OFF; this particular design protects installers and users fro...

An improved active snubber cell is proposed for ZVT-ZCT PWM DC-DC boost converter. Zero voltage transition (ZVT) turn on and zero current transition (ZCT) turn off is provided by this active snubber cell. There is no extra current or voltage stresses on the main switch. Also, zero current switching (ZCS) turn on ZCT turn off is provided for the auxiliary switch. Although there is no extra volta...

This paper presents the design of simple but powerful soft switching scheme for a DCDC Boost Converter with a closed loop control. A new novel soft switching scheme is proposed with a single switch and minimum components which offers load independent operations. The only switch used in this converter is switched ON at zero current and switched OFF at zero voltage .The proposed Controller is use...

Results about energy capture from the environment associated with the self-powering of a wireless sensor network (WSN) for structural health monitoring of aircrafts (SHM) are presented. Thermal gradients taking place during specific flight phases are converted into electrical energy by using a small water tank coupled to a thermoelectric generator which output is connected to a storage circuit....

Conventional two-state dc to dc voltage converters have in their small signal transfer function a right half planzero in pole-zero plane whichthis zero result in speed reduction and lowfrequency operation, especially, because position of the zero is not fixed andmovesby the load variation. To remedy this problem the tri-state boost converters have been introduced. These converters haven’t the m...
