Efficiency enhancement of solar PV powered micro-integrated high frequency isolated vehicle battery charging converter. This Paper proposes a method to improve the efficiency of charging the battery used in autonomous electric vehicle powered by foldable roofmounted solar photovoltaic PV generation system.

The conventional vehicle battery charging The conventional vehicle battery charging application from solar PV consists of a boost converter in the frontend followed by a full bridge converter with discrete switches. Here an attempt is made on the total scheme with a micro integrated package to have better conversion efficiency with high power density.

The total system is controlled digitally incorporating zero voltage transition ZVT in the full bridge conversion. A typical specification with a power level of W was targeted and achieved. Save to Library. Due to the ZVT-ZCT, the resonant components with low values are used that results in the increase of switching frequency. High current multiphase buck converters found applications in advanced data control, solid state lasers, communication equipment and Pentium processors etc.

The zero-voltage-transition and zero current transition operation of the proposed converter is presented through theoretical analysis.

A simple design method for auxiliary circuit is discussed. High current multiphase buck converters MBC are used in computing, graphics, and telecom applications.

To achieve high power-density converters and high-performance, the switching frequency of the converters need to be increased. The traditional hard switching pulse-width-modulation PWM converters operating at high frequency is limited because of substantial switching loss.

In these converters, the zero-voltage switching condition which is bestowed by auxiliary circuit for wide line and load ranges provides minimum voltage and current stresses on devices. Another way to achieve high-performance and high-power density converters is adopting the multiphase conversion technique [5]-[8]. With the interleaved operation, small size inductors can be used keeping low current ripple at the input and output capacitor filters, and high dynamic performance can be achieved since the operating frequency of input and output filter capacitors is increased by n times for n-phase converters.

Higher dynamic performance and higher power-density power conversion can be achieved if both ZVT-ZCT and multiphase conversion techniques are combined. Because the switching frequency is equal to the inductor current ripple frequency, the switching frequency is limited between kHz to kHz []. When the inductor current slew rate is increased with a smaller inductance value to improve the transient response, then the inductor current ripple also increases.

It is not only a harmful action for the high-side switch due to larger turn-off loss, but also for the low-side switch due to a larger conduction loss.

It also increases the inductor winding losses. This conflict limits the average inductor current in each channel []. Moreover, there is a tradeoff between efficiency and transient response. As a result, these technical conflicts do not only increase the costs and sacrifice the power density, but also difficultly meet the power requirements of future microprocessors before the technical conflicts are resolved []. It is possible to use The ZVS is nearly independent from the load range.

Principles of operation, analysis and simulation results are presented. In this study, a new boost converter with an active snubber cell is proposed. The active snubber cell provides main switch to turn on with zero voltage transition ZVT and to turn off with zero current transition ZCT.

The proposed The proposed converter incorporating this snubber cell can operate with soft switching at high frequencies. Also, in this converter all semiconductor devices operate with soft switching. There is no additional voltage stress across the main and auxiliary components. The converter has a simple structure, minimum number of components and ease of control as well. The Fuzzy Logic FL controller with two inputs maintains the load voltage by detecting the voltage variations through d-q transformation technique that is connected in feedback of these converter.

The presented theoretical analysis is measured in simulation results by 1kW converter. Here output power upto v is given Also, the overall efficiency of the new converter has reached a value of Fathima Parveen. Some of the stringent requirements of these applications can be Some of the stringent requirements of these applications can be achieved by high-frequency switching. On the other hand, the use of high switching frequency may degrade the overall system efficiency, what can be alleviated by the utilization of soft-switching techniques.

In this paper, it is proposed a generic soft-switching diagram, which can generate topologies for turn-on snubbers, zero voltage transition ZVT and zero current and zero voltage transition ZCZVT inverters. This approach facilitates the understanding of these techniques by newcomers, as well senior engineers.

Therefore, the distinctness of the merits and disadvantages of each soft-switching technique becomes much easier. Zero-voltage transition PWM converters: a classification methodology.

Thread starter rakesh Start date Nov 17, Status Not open for further replies. I have to design a boost converter with zvt for 4-stage interleaved boost converter for v dc output from 3ph supply of v,50hz, switching frequency 20khz.

Can u give a detailed Description so that we can help ZVT abbreviation?? Click to expand Four phases interleaved boost phases from a 3 phase AC feed? So are you talking about running four separate three-phase rectifiers in parallel and interleaving their switching? That sounds
