Abstract

The invention provides a control system and method for improving the stability of output voltage of a power supply, and relates to the technical field of power supply control. A compensation capacitor is pre-charged through a compensation capacitor pre-charging loop, a load capacitor is pre-charged through a load capacitor pre-charging loop, and it is guaranteed that voltages at the two ends of all the compensation capacitors and the load capacitor are consistent; and when the compensation parameters are dynamically switched, charges cannot be redistributed among the capacitors due to potential difference, so that the system output cannot be suddenly changed when the compensation parameters are switched again. The beneficial effect of the invention is that the problem that the output voltage of the power supply is unstable in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of power supply control, and in particular relates to a control system and a control method for improving the output voltage stability of a power supply. Background technique [0002] In the wafer and chip test system, the voltage stability of the test equipment is very high, and slight instability will have a negative impact on the accuracy of the test data, and even cause damage to the chip. Therefore, it is necessary to control the power supply voltage to avoid fluctuations Wait for the power supply voltage instability problem. Contents of the invention [0003] The invention provides a control system and a control method for improving the stability of the output voltage of the power supply, which solves the problems of unstable output voltage of the power supply in the prior art. [0004] In a first aspect of the present invention, a control system for improving the stability of the output voltage of ...
