Abstract

The invention discloses a single-tube and high-gain direct-current voltage boosting circuit with additional electrical potential excitation and superposition and belongs to the technical field of power conversion circuits. In a switching-on / off process of a switching tube, an auxiliary capacitor is charged by an auxiliary inductor element parallel to a boosting inductor to form additional electrical potential; the switching tube is used for controlling a boosting inductor element to be changed by power supply voltage and auxiliary electrical potential and the parallel auxiliary inductor element to be charged by the power supply voltage; in a turning-on process of the switching tube, the power supply voltage and the additional electrical potential are used for carrying out superposition and excitation on the boosting inductor element and the boosting inductor element obtains more energy; in a switching-on / off process of a main switching tube, boosting voltage of the boosting inductor, the power supply voltage and the additional electrical potential are used for discharging toward a load; an output end obtains high-gain direct-current voltage and is boosted and transformed; meanwhile, the circuit provided by the invention has a simple circuit mode and the efficiency of circuit transmission power is high.

Description

technical field [0001] The invention belongs to the technical field of power conversion circuits, in particular to a single-tube high-gain DC voltage boosting circuit with additional potential excitation and superposition. Background technique [0002] With the development of economy and society, the tension of energy demand is intensified, and the negative impact of fossil energy is prominent. New energy power generation systems such as wind energy and solar energy are developing vigorously and gradually being popularized and applied. However, in practical applications, the influence of random factors such as wind speed, light, and climate restricts the wide application of new energy power generation systems. How to make wind power and solar power generation devices generate stable power under changing environmental conditions such as wind, light, and climate is a factor that must be considered in new energy power generation systems. [0003] In photovoltaic power generati...
