Topological Derivation of DC-DC Multiplier Converters

Abstract— This paper extends the traditional family of PWM DC-DC converters. By employing voltage capacitor-multipliers, converters provide high voltage gains. The capacitor multiplier of each converter is driven by the same transistor of the well-known basic topology. The main features of these new converters are: (i) high-voltage gain without extreme duty cycles and transformerless. Therefore, high switching frequency is allowed; (ii) low voltage stress in switching devices; and (iii) more output levels can be added without modifying the main circuit. These features are highly desirable in some applications such as renewable energy generation systems.
