Positive output Luo converters: voltage lift technique

Abstract

The voltage lift technique is a popular method that is widely applied in electronic circuit design. Because of the effect of parasitic elements the output voltage and power transfer efficiency of DC–DC converters are limited. The voltage lift technique opens a good way to improve circuit characteristics. After long-term research, this technique has been successfully applied for DC–DC converters. Positive output Luo converters are a series of new DC–DC step-up (boost) converters, which were developed from prototypes using voltage lift technique. These converters perform positive to positive DC–DC voltage increasing conversion with high power density, high efficiency and cheap topology in simple structure. They are different from other existing DC–DC step-up converters and possess many advantages including a high output voltage with small ripples. Therefore, these converters will be widely used in computer peripheral equipment and industrial applications, especially for high output voltage projects.
