A New Control Method of a Current Balancer in Single-Phase Three-Wire Secondary Distribution Systems Using the Correlation and Cross-Correlation Coefficients

Language：English Publisher：IEEE

This paper proposes a new control method of a current balancer for single-phase three-wire secondary distribution systems using the correlation and cross-correlation coefficients to reduce the capacity of the three-leg PWM inverter, which performs the current balancer. The components correlative and cross-correlative to the primary side voltage waveform, which correspond to the active and reactive currents, are calculated from the detected load currents on each feeder. Then the reactive and unbalanced-active currents are compensated on the source side. The balanced source currents with the power factor of 0.9 are obtained in each feeder. This imperfect compensation of the reactive power reduces the capacity of both the three-leg PWM inverter and do capacitor. The basic principle of the proposed method is discussed in detail, and then confirmed by digital computer simulation. A proto-type experimental system is constructed and tested. Experimental results demonstrate that the balanced source currents with the power factor of 0.9 are obtained in spite of unbalanced load currents reducing the capacity of the three-leg PWM inverter.

A Novel Real-Time Detection Method of Active and Reactive Currents for Single-Phase Active Power Filters

IEICE technical report 107 ( 149 ) 39 - 44 2007.7

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

This paper proposes the simplest real-time detection method of the fundamental active and reactive currents in single-phase circuits. The proposed method uses only four multipliers and two LPFs for detecting the fundamental active and reactive currents with a PLL circuit. The basic principle of the proposed detection method is discussed in detail, and the proposed method is applied to a previously proposed single-phase shunt active filter for consumer electronic equipment. Digital computer simulation is used to confirm the validity of the proposed detection method. A reduce-scale experimental model is constructed and tested. Experimental results demonstrate the excellent practicability of the proposed detection method.

Operation Charactersitics of an Asymmetrical Auxiliary Edge-Resonant Snubber-assisted ZCS-PWM DC-DC Converter

MISHIMA Tomokazu, HIRAKI Eiji, TANAKA Toshihiko, NAKAOKA Mutsuo

IEICE technical report 106 ( 494 ) 7 - 12 2007.1

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

In recent years, research and development on a low voltage / high current output-type DC-DC converter have been attracting special interests in telecommunication and information power supplies as well as automotive electric power systems. For reducing switching losses and EMI levels in those electric power applications, several soft switching DC-DC converter topologies have been discussed with their control schemes. In this study, a novel high-frequcny transformer linked ZCS-PWM DC-DC converter that is constructed with an asymmetrical auxiliary resonant snubber-assisted half-bridge inverter and a current doubler rectifier is proposed. By investigating the operation and characteristics of this DC-DC converter, the ZCS scheme with the auxiliary snubber is verified to be effective, and design considerations of the resonant circuit parameters including the high- frequency transformer is described in this paper.
