Burst mode power supply method and burst mode power supply apparatus
First Claim
1. A burst mode power supply method comprising:
- a. fixing a pulse quantity of each of burst clumps of a power supply apparatus (10), a pulse frequency of each of the burst clumps of the power supply apparatus (10) and a pulse duty cycle of each of the burst clumps of the power supply apparatus (10) when the power supply apparatus (10) works in a burst mode,wherein the pulse frequency of each of the burst clumps and the pulse duty cycle of each of the burst clumps are the same in the burst mode;
only a burst frequency of the burst clump is changed according to a load (20) in the burst mode;
the burst frequency increases if the load (20) increases in the burst mode thus rendering a quantity of the burst clumps increases;
the burst frequency decreases if the load (20) decreases in the burst mode thus rendering the quantity of the burst clumps decreases.

Abstract
A power supply apparatus (10) includes a voltage input side (102), a power switch circuit (104), a voltage output side (106) and a pulse width modulation signal generating circuit (108). According to a pulse width modulation signal (112), the pulse width modulation signal generating circuit (108) controls the power switch circuit (104), so that the power supply apparatus (10) enters a burst mode. A pulse quantity of each of burst clumps of the power supply apparatus (10), a pulse frequency of each of the burst clumps of the power supply apparatus (10) and a pulse duty cycle of each of the burst clumps of the power supply apparatus (10) are fixed and constant after the power supply apparatus (10) enters the burst mode.
