Title:
BOOST DIRECT CURRENT-DIRECT CURRENT CONVERTER
Document Type and Number:
WIPO Patent Application WO/2017/190430
Kind Code:
A1
Abstract:
A boost direct current-direct current converter, comprising: a booster circuit (10), a protection circuit (20), a detection circuit (30), a feedback control circuit (40) and a feedback circuit (50). The booster circuit (10) outputs a voltage to the outside via the protection circuit (20), and the protection circuit (20) controls the voltage output by the booster circuit (10) to the outside according to an output current of the booster circuit (10). The detection circuit (30) detects an output voltage (Vout) of the protection circuit (20), and controls, according to the detected output voltage, whether the feedback control circuit (40) performs feedback control on the booster circuit (10) according to the feedback voltage of the feedback circuit (50). By means of adding a protection circuit and a detection circuit, the boost direct current-direct current converter completely disables the outputting when a short circuit occurs during outputting, thereby achieving the effects of short-circuit protection and reducing power consumption.
