دانلود کتاب DC/DC CONVERTERS

DC/DC conversion technology is the main branch of Power Electronics and is progressing rapidly. Recent reports indicate that the production of DC/ DC converters occupies the largest percentage of the total turnover of all conversion equipment productions. Based on incomplete statistics, there are more than 500 topologies of DC/DC converters existing. Many new topologies are still created every year.

It is a lofty undertaking to write about the large number of DC/DC converters. The authors have sorted these converters into six generations since 2000. This systematical work is very helpful for understanding DC/DC converter evolution and development. The categories are listed below:
1. The first generation (classical/traditional) converters
2. The second generation (multiple quadrant) converters
3. The third generation (switched component) converters
4. The fourth generation (soft switching) converters
5. The fifth generation (synchronous rectifier) converters
6. The sixth generation (multiple element resonant power) converters
More than 300 prototypes of the first generation converters have been developed in the past 80 years. The purpose of this book is to provide information about essential DC/ DC converters that is both concise and useful for engineering students and practicing professionals. It is well organized in 410 pages and 200 diagrams to introduce more than 80 topologies of the essential DC/DC converters originally developed by the authors. All topologies are novel approaches and great contributions to modern power electronics. They are sorted in three groups:
• The voltage-lift converters
• The super-lift converters
• The ultra-lift converter
The voltage lift technique is a popular method that is widely applied in electronic circuit design. Applying this technique effectively overcomes the effects of parasitic elements and greatly increases the output voltage. Therefore, these DC/DC converters can convert the source voltage into a higher output voltage with high power efficiency, high power density and a simple structure. It is applied in the periodical switching circuit. Usually, a capacitor is charged during switching-on by certain voltage. This charged capacitor voltage can be arranged on top-up to output voltage during switching-off. Therefore, the output voltage can be increased. A typical example is the sawtooth- wave generator with voltage lift circuit.
Voltage lift technique has its output voltage increasing in arithmetic progression, stage by stage. Super lift technique is more powerful than voltagelift technique. The output voltage transfer gain of super-lift converters can be very high, and increases in geometric progression, stage by stage. It effectively enhances the voltage transfer gain in power series. Four series of super-lift converters created by the authors are introduced in this book. Some industrial applications verified their versatile and powerful characteristics. Super-lift technique is an outstanding achievement in DC/DC conversion technology.
