This paper proposes a frequency separation type current control system for a grid-connected single-phase five-level inverter. The proposed control system realizes high tracking performance and high disturbance suppression performance. To obtain high tracking performance to the sinusoidal reference signal, a repetitive controller is applied to the current controller. The current controller with a repetitive...
This paper proposes a new power factor correction method using an inverter-driven interior permanent magnet (IPM) motor. The proposed system realizes the high power factor of a single-phase diode rectifier by using a three-phase pulsewidth modulation inverter and an IPM motor. The proposed converter consists of a single-phase diode rectifier, a small film capacitor at the dc link (14 and...
