Abstract
The invention belongs to the technical field of circuits, and discloses a method for dynamically improving wave transmission of a circuit driver, which comprises the following steps that: an MCU (Microprogrammed Control Unit) performs loop operation, updates and loads a loop operation result on the driver and determines a circuit structure, so that the time t required for updating the driver is determined, and the time for updating the driver is t earlier than the time for loading the driver; the method has the advantages that the updating time of the LLC driver is made to be ahead of the loading time by means of the interrupt request function of the main timer of the control chip, the driving response speed is increased, compared with a traditional driving updating mode, the LLC driver can respond to updating more quickly, the driving updating strategy can complete updating one cycle ahead of time, and the driving updating speed is increased. The strategy has the advantages of increasing the loop phase margin, reducing the driving response delay and the like.
