Abstract

The invention discloses a single-tube high-gain direct-current voltage enhancement conversion circuit with additional electric potential superposition output, and belongs to the technical field of an electric power conversion circuit. According to the circuit, conversion control is improved by high gain of a direct current voltage implemented by a single switching tube; in the switch-on and switch-off process of the switching tube, an auxiliary capacitor is charged by a parallel inductor to form additional electric potential; a pump lifting voltage, formed by a voltage boosting inductance element which is charged and then discharged in the circuit, is connected with the additional electric potential in a sequence polar serial connection manner to supply power for a load so as to improve the input direct current voltage; the charging of the voltage boosting inductance element and a parallel inductance element, the self-induction electric potential of a voltage boosting inductor and state conversion of the sequence polar series discharging of the capacitor voltage charged by the parallel inductor can be controlled by the single switching tube, so that output voltage gain which is much higher than that of a single-stage voltage boosting chopping wave conversion circuit can be obtained; and meanwhile, the circuit is simple in control modal state, and high in circuit power transferring efficiency.

Description

technical field [0001] The invention belongs to the technical field of power conversion circuits, and in particular relates to a single-tube high-gain DC voltage boost conversion circuit with additional potential superposition output. 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 po...
