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 power 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 power converters. Positive output Luo converters are a series of new DC-DC step-up (boost) converters, which were developed from prototypes using the 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 power 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
