The generation mechanism of inter-harmonics for medium-frequency power supply is deeply analyzed based on its circuit topological structure, which badly impact the safe and stable operating state of electric power equipment. First of all, the mathematical models of harmonic transmission characteristics in rectifier and half bridge inverter are established. Then, the mathematical models of inter-harmonic in medium-frequency power supply are derived by combining harmonic transmission characteristics of both. Finally, medium-frequency power supply with twelve pulses rectifier is analyzed by simulating and measuring data. The simulation and measurement results show that inter-harmonics emission characteristics of medium-frequency power supply is accurately described by these mathematical models, and the accuracy of models can meet the demand of engineering application as well.
