Boosting circuit with single input and double independent output and inversion device thereof

Abstract

The invention discloses a boosting circuit with a single input and double independent output and an inversion device thereof. The boosting circuit comprises a DC input, a first independent boosting unit and a second independent boosting unit, and is characterized in that the first independent boosting unit and the second independent boosting unit improve DC output of the boosting circuit with a single input and double independent output in a mutually independent manner. The first independent boosting unit and the second independent boosting unit are set, so that two independent DC outputs can be generated in a boosting manner by only one DC input, and values of the two DC outputs can be independently adjusted. Two DC output buses can be provided for an external load, and initial voltage of the two DC output buses can be adjusted according to the size of the external load, so that the boosted output voltage is enabled to be more fit for the working voltage of the external load, the external load is ensured to stay at the best working condition, the universality of the boosting circuit with a single input and double independent output is improved, and the application range is expanded.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a boost circuit with single input and double independent outputs and an inverter device thereof. Background technique [0002] The boost circuit is widely used in various power electronic devices. The existing boost circuit mainly includes a switch tube, an inductor and a capacitor. When the switch tube is turned on, the inductor in the boost circuit can charge and store energy; when the switch tube is turned off, When off, the inductor in the boost circuit discharges and releases energy, and charges the capacitor in the boost circuit, thereby increasing the voltage for the external load connected in parallel with the capacitor. However, most of the existing boost circuits generate one output voltage for one input voltage. If the equipment requires multiple output voltages, multiple boost circuits need to be installed, which increases the input cost and complicates the ...

Problems solved by technology

However, most of the existing booster circuits generate an output voltage for one input voltage. If the equipment requires multiple output voltages, multiple booster circuits need to be installed, which increases the input cost and makes the circuit more complicated.

In order to solve this problem, there are also some booster circuits that generate multiple output voltages from one input voltage, but the output voltages are not controlled independently of each other, so that the size of each output voltage cannot be adjusted independently, so that the application Restricted, poor versatility
