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....

converter generally consists of power semiconductor devices which are operate as an electronic switches. Operation of these switching devices causes inherently nonlinear characteristic to the DC-DC Converters include buck-boost converter. Proposed system consists of development of fuzzy logic controller for generating control PWM pulses of required duty cycle for MOSFET of the buck-boost conver...

This paper presents the principles of state-space average modeling of DC-DC Boost converters operating in the Discontinuous Conduction Mode (DCM) which occurs in converters due to low load current operation. The switching ripples in inductor current or capacitor voltage cause polarity reversal of the applied switch current or voltage and thus a zero current mode is reached. Modern converters ar...

This paper proposes a new passive snubber for enhancing the power conversion efficiency on a single phase ac-dc power factor correction (PFC) converter based on boost topology for battery charging systems. Soft switching can be achieved in the proposed converter with the proposed auxillary passive snubber circuit which is added to the conventional boost PFC converter. The converter switch is pr...

The power converter is one of the essential elements for effective use of renewable power sources. This paper focuses on the development of a circuit simulation model for maximum power point tracking (MPPT) evaluation of solar power that involves using different buck-boost power converter topologies; including SEPIC, Zeta, and four-switch type buck-boost DC/DC converters. The circuit simulation...

The need for renewable and more efficient electrical energy generation, distribution and conversion drives exploration of new power conversion topologies and development of advanced power component technologies. Recently reintroduced multilevel boost converter topologies, by allowing use of new, efficient but relatively low voltage power devices at higher voltage and power levels, are becoming ...

This paper presents a high-efficiency nonisolated interleaved dc–dc inductor boost converter with a common active clamp circuit. Interleaved boost converters are highly preferred as it reduces the ripple current. A boost converter is used to clamp the voltage stresses of all the switches in the interleaved converter which is caused by the leakage inductances. The leakage energies of the interle...

In this paper, direct model predictive control (DMPC) of the noninverting buck-boost DC-DC converter with magnetic coupling between input and output is proposed. Unlike most other converters, subject has advantage exhibiting minimum phase behavior in boost mode. However, a major issue that arises classical dead zone near transition buck The reason for practically unrealizable duty cycles, which...
