Abstract

The invention provides a burst mode-type power supply method and a burst mode-type power supply device. The burst mode-type power supply device comprises a voltage input end, a power switching circuit, a voltage output end and a pulse width modulation signal generation circuit, wherein the pulse width modulation signal generation circuit controls the power switching circuit through a pulse width modulation signal, so that the burst mode-type power supply device enters a burst mode. After the burst mode-type power supply device enters the burst mode, the pulse quantity in each burst clump of the burst mode-type power supply device, the pulse frequency in each burst clump of the burst mode-type power supply device and the pulse duty cycle in each burst clump of the burst mode-type power supply device are fixed.

Description

technical field [0001] The invention relates to a power supply method and a power supply device, in particular to a pulse intermittent mode power supply method and a pulse intermittent mode power supply device. Background technique [0002] When the power supply device is in the standby mode or the light load mode, the power supply device will enter a burst mode to save energy. [0003] When a related art power supply device operates in the burst mode and a load connected to the related art power supply device changes (increases or decreases), each burst clump of the related art power supply device The number of pulses (pulse quantity), the pulse frequency (pulse frequency) in each pulse group of the power supply device of the related art, the pulse duty cycle of each pulse group of the power supply device of the related art (pulse duty cycle) or the burst frequency (burst frequency) of the pulse group of the power supply device of the related technology may change; therefo...
