Abstract

The invention discloses a boost conversion system and a voltage converter. The boost conversion system comprises a first boost branch circuit, a second boost branch circuit, a first switch unit, a second switch unit, a first energy storage unit, a second energy storage unit and a control unit, wherein the first boost branch circuit and the second boost branch circuit are connected with the first energy storage unit and the second energy storage unit; the first energy storage unit is connected with the first switch unit, the second energy storage unit is connected with the second switch unit, and the control unit is used for controlling on and off of switch tubes in the first boost branch circuit, the second boost branch circuit, the first switch unit and the second switch unit. so as to provide power supply voltage for a load according to the voltage of a direct-current power supply, the voltage of the first boost branch circuit and the voltage of the first energy storage unit, or providing power supply voltage for the load according to the voltage of the direct-current power supply, the voltage of the second boost branch circuit and the voltage of the second energy storage unit. In this way, the boost conversion efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, in particular to a boost conversion system and a voltage converter. Background technique [0002] With the further development of technology, various portable devices such as mobile phones, tablet computers, digital cameras, MP3 players, etc. have become popular. Batteries are often used in applications such as display backlighting, audio amplifiers, or piezoelectric haptic actuators, as described above. For example, each portable device may include a liquid crystal display (LCD), which itself does not emit light and requires a backlight to provide illumination in order to produce a visible image. Therefore, its backlight can be formed by multiple light-emitting diodes (LEDs), and each LED usually requires 3.3V to emit light. Depending on the number of LEDs, the backlight may require a supply voltage of up to 20V, a boost converter can be coupled between a source (e.g., a ...
