description The invention relates to a distributed pulse width modulation method based on multi-core cooperative work. The hardware architecture adopts a master-slave control mode, and is composed of a main module and a plurality of sub modules. The main module and the sub modules are connected by means of 485 communication. Each sub module contains an H bridge unit. The H bridge units are cascaded, and are then output via an LC filter circuit. The method specifically comprises the following steps: the parameters of the main module are initialized; the main module updates the state of the sub modules, andcalculates the total error value of the current output voltage; the main module traverses the sub modules to seek an optimal output unit; the selected optimal output unit calculates the delay time and outputs a new level; and fault protection is offered to the sub modules. The control ability and computation ability of the overall equipment are improved. The main module controls the sub modules through communication inte
