Embodiment Construction

[0038] Please refer to Figure 2A , is a schematic diagram of a feedforward control system according to an embodiment of the present invention. The present invention discloses a pulse current feedforward control system 200 , which includes a processing unit 210 and a power supply unit 220 . Wherein, the processing unit 210 may be a graphics processing unit (GPU) or a central processing unit (CPU), but not limited thereto. Moreover, the power supply unit 220 of this embodiment may be a pulse width modulation power supply (PWM Unit), but this is not limited in the present invention.

[0039] The processing unit 210 can optionally generate a feed-forward demand signal S1. The power supply unit 220 is electrically connected to the processing unit 210 , and the power supply unit 220 normally provides an initial current C1 to the processing unit 210 , and the power supply unit 220 can also selectively provide a modulated current C2 to the processing unit 210 .

Abstract

The invention relates to a feed-forward control method for a pulse current. The feed-forward control method comprises the following steps of: firstly, normally supplying an initial current to a processing unit by a power supply unit; and then pre-sending a feed-forward demand signal to the power supply unit by the processing unit before the processing unit changes the calculating efficacy, and correspondingly supplying a modulation current to the processing unit according to the feed-forward demand signal by the power supply unit.

Description

【Technical field】 [0001] The invention relates to a control system and a control method thereof, in particular to a pulse current feed-forward control system and a control method thereof. 【Background technique】 [0002] The processing unit in a general computer, such as a central processing unit (Central Processing Unit, CPU) or a graphics processing unit (Graphic Processing Unit, GPU), etc., will be responsible for adjusting and coordinating the required power according to the amount of data processing. The power required by the processing unit needs to be controlled by a Pulse Width Modulation Unit (PWM Unit). [0003] The pulse width modulation unit is an electronic component located on the computer motherboard responsible for providing current to the processing unit. The pulse width modulation unit will change the voltage of the processing unit to adjust the output current to the processing unit, regardless of the processing unit. When the amount of data processing incr...
