Optimization Design of Three-Phase Balanced Power Supply for Vehicle Mobile Power

This paper analyzed the harm of three-phase unbalanced power supply of vehicle mobile power supply to generator set electrical equipment and communication system, and the cause of the harm is analyzed. The three-phase balance control box is designed by adopting the design concept of “three input one output” and “rectifier inverter”. Through the comparison of the experimental data, the feasibility of the three-phase balance control box for the three-phase balance adjustment of the external power supply of the vehicle mobile power supply is verified, so as to achieves the optimization of the three-phase balance power supply and improves the reliability and safety of the external power supply of the vehicle mobile power supply.
