Logic modeling method for three-phase uncontrolled rectifier

The invention relates to a three-phase uncontrolled rectifier main circuit mathematical model modeling method, in particular to a three-phase uncontrolled rectifier logic modeling method. According to the method, a logic modeling mode is adopted, building of a mathematical model of a main circuit of the three-phase uncontrolled rectifier is achieved, and logic modeling comprises a voltage calculation part model, a diode conduction logic judgment model and a three-phase current operation logic model. And combining the voltage calculation part model, the diode conduction logic judgment model and the three-phase current operation logic model to form a mathematical model of the whole three-phase uncontrolled rectifier main circuit. According to the three-phase uncontrolled rectifier logic modeling method applied to semi-physical simulation joint debugging, a logic modeling mode is adopted, building of a main circuit mathematical model of the three-phase uncontrolled rectifier is achieved, a main circuit model for
