Abstract

The present invention relates to the technical field of power electronics, in particular to a boost converter, comprising a first input port, a first output port, a main line, an acquisition circuit, a control circuit, a pulse width modulation circuit and a drive circuit, the main line is connected to the first Between an input port and the first output port, the control circuit receives a first reference signal and a second reference signal, the acquisition circuit is coupled to collect the output current to generate a first collection signal, and collect the output voltage to generate a second collection signal, The control circuit receives the first collection signal, the control circuit receives the second collection signal, the control circuit compares the first collection signal with the first reference signal, and compares the second collection signal with the second reference signal, and according to the two comparison results A comparison voltage is output, and the pulse width modulation circuit and the driving circuit are driven in the main line to generate the output voltage and output current after feedback adjustment, which can make the loop compensation occupy a small area and the loop transition is smooth.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a boost converter. Background technique [0002] The switch-type step-up DC-to-DC converter has the characteristics of high efficiency, wide input voltage range, and large output current, and is widely used in various fields, especially in battery discharge applications. It is necessary to boost the battery voltage to a stable 5V output before it can be used by portable devices. [0003] Batteries are widely used today, and the switch-type boost DC-to-DC converter is an indispensable converter in the battery discharge link, which is used to convert the battery voltage into a standard voltage output. For the purpose of protecting the battery, an accurate output current threshold must be set to protect the battery and boost DC-to-DC post-stage equipment. However, traditional step-up DC-to-DC converters often do not have such protection, or even if protection is provided...
