Abstract :
In large-scale inverter systems, a DC circuit connects the rectifier and inverter. And the DC circuit has DC capacitors to smooth and stabilize the DC voltage and the inductance of distribution wires. Therefore, it is possible that a harmonic resonance phenomenon is induced in this circuit. This harmonic resonance phenomenon depends on the characteristics of the DC circuit and the harmonic current generated by the rectifier and inverter. This paper describes the analysis of the input current of the inverter system caused by PWM control and the harmonic resonance phenomenon induced in the DC circuit
