ABSTRACT
The ordinary DC/DC converter has limited voltage transfer gain. Considering the effects of the component called parasitic elements, the conduction duty cycle k can only be 0.1 < k < 0.9. This restriction blocks ordinary DC/DC converter voltage transfer gain increase. The VL technique is a common method used in electronics circuitry design to amplify output voltage. Using this technique in DC/DC conversion technology, we can design, stage by stage, VL power converters with high voltage transfer gains in arithmetic progression. It opens the way to significantly increase the voltage transfer gain of DC/DC converters. Using this technique, the following series of VL converters are designed [1,2]:
• P/O Luo-converters • N/O Luo-converters • D/O Luo-converters • VL Cúk-converters • VL SEPIC • Other VL D/O converters • Switched-capacitorized (SC) converters.
