Modularized inverter power supply control method for intelligent start and stop polling mechanism

The invention discloses a modularized inverter power supply control method for an intelligent start and stop polling mechanism. The method comprises the steps of intelligent starting, intelligent stopping, polling starting and polling stopping. According to the modularized inverter power supply control method for the intelligent start and stop polling mechanism, intelligent control over starting and stopping of power modules in a system is achieved, when the power modules are started, new power modules are connected in around a maximum working point, when the power modules are closed, redundant power modules are closed around a 20% power point, intelligent startup and shutdown control over the integral system is achieved, unnecessary power loss of the system is reduced, and system efficiency is improved. Polling control is carried out on working of the power modules in the system, the facts that each module can serve as a first module to run and each module can serve as a first module to be stopped are achieved, therefore equalization control over the working time of each module can be achieved to the maximum degree, and the service life of the system is prolonged.
