This paper proposes a novel single-phase to three-phase power converter, which based on current-fed topology. The proposed power converter doesn't require electrolytic capacitor and large inductance reactor. The proposed control method obtains high power factor operation and variable speed control for IPMSM. By using boost voltage characteristics of the proposed converter, the converter controls high...
This paper proposes a novel control strategy for IPMSM drive system. The proposed single-phase to three-phase power converter does not require a reactor and an electrolytic capacitor at dc-link, and obtains unity input power factor. The proposed control method improves the source current waveform at any load conditions by using the feedback control. The proposed control system is constructed by using...
This paper describes single-phase uninterruptible power supply (UPS) with active filter and flywheel. The UPS consists of a diode rectifier, a single-phase inverter, a flywheel energy storage unit with PM motor/generator and a three-phase inverter, not using a bulky electrolytic capacitor, battery and filter reactor. It contains many excellent characteristics: small size, lightweight and maintenance-free...
This paper proposes a novel single-phase to three-phase converter topology, which aims at the source side power ripple. The proposed system obtains unity power factor of single-phase rectifier without a reactor and a bulky electrolytic capacitor. Source side energy provides directly to the motor without smoothing at the dc-bus voltage. This paper describes that the proposed method achieves the power...
