   A Three-Phase Current Source Inverter For Energy Storage System With Batteries
By Shoji Iida, Tomohiro Kawasaki And Shigeo Masukawa [View]
[Download]

Abstract: A novel PWM control scheme for the three-phase current source inverter is proposed. It is appropriate to the energy storage system with batteries. Respective pulse widths composing output currents are decided in proportion to the corresponding system ac voltage. PWM control pattern can be simplified effectively by overlapping the control signals to the plural devices. Several experimental discussions for the discharging characteristics with the proposed inverter are presented in detail in this paper.

Abstract: The paper introduces a sunrise power semiconductor switching device called IGCT. Converters based on IGCTs might contribute in near future to the quality of electric drives. Longterm practical results comfirm their advantages, especially high reliability.

   Unified Algorithm And Different Topologies Of Single-Phase Ac/dc Converters With Unitary Power Factor
By Yang Xijun, Ling Zhibin, Chen Hongping, Ye Pengsheng [View]
[Download]

Abstract: In the paper, a group of direct boost AC/DC converters are mainly dealt with. By analysis, they can employ the unified control principle |the boost power factor correction algorithm. In addition, their conversion topologies are very simple and practical, and they can be used as pre-regulator of inverter air-conditioners. By placing the power device and boost inductor in different positions, many new AC/DC converters can be deduced from the original single-phase controlled bridge AC/DC converters, a few of which have been mentioned by some former researchers. Why they have the same working principle and why they can be employed as single-phase boost AC/DC with unitary power factor are depicted in detail. Moreover, for example, one of the single-phase AC/DC converters, named low-end semi-controlled bridge AC/DC converter is simulated and implemented as the front-end circuit of a new-style DC inverter air-conditioner. Consequently, the input power factor is one approximately and the power output exceeds 2.5kW. Other deduced AC/DC converters are all simulated also. The simulated and experimental results are consistent, as proves the validity of the theoretical analysis.
