Abstract
A boost converter includes a bridge rectifier, a first capacitor, a supply circuit, a first inductor, a current compensation circuit, a power switch element, an output stage circuit, a feedback compensation circuit, and an MCU (Microcontroller Unit). The bridge rectifier generates a rectified voltage according to a first input voltage and a second input voltage. The first inductor receives the rectified voltage. The output stage circuit is coupled to the first inductor and the current compensation circuit, and generates an output voltage. The feedback compensation circuit generates a feedback voltage according to the output voltage. The MCU monitors and limits a duty cycle of a clock voltage. If the duty cycle reaches a maximum threshold value, the MCU will enable the current compensation circuit to provide an additional current, thereby increasing the output power of the boost converter.
