Because of its totally soft-switched operation, isolated output stage and bidirectional power flow, the proposed converter system is suited for interfacing a new energy system, such as a PV (photovoltaic) system having a battery, with AC system line. The restriction of output vector transition in applying SVM technique is discussed first. Then, a suitable pattern which satisfies soft-switching operation is proposed. The validity of the proposed scheme has been proved with simulation study using PSIM and experimental results with DSP based prototype system.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

Parallel operation of many power-MOSFET elements is investigated in room and liquid nitrogen temperatures. The total on-state resistance shows lowered value in parallel connected and cooled down conditions, and the reduced resistance is effective for operational loss reduction of the converter circuit. The bi-directional switching unit with four power-MOSFET elements is proposed, which can be applied to the self commutated type AC/DC converter. Another type of AC/DC converter using power-MOSFET consists of a three phase synchronous rectifier circuit, which is suitable to output one directional high DC current.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

A clamped-mode series resonant converter (CM-SRC) has six operating modes in the static operation. The modes depend on the circuit parameters, states, and the variation of each switching interval. The analysis of operating mode has already been achieved in the static state. However, the dynamic mode transition of CM-SRC caused by load disturbances and the output control is not well understood. In this paper, it is clarified that output control induces new operating modes which have never been observed in the static operation experimentally and numerically.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

In order to implement the equivalent inertia of the entire elevator system, the conventional simulators have generally utilized mechanical inertia (flywheel) with large radius, which makes the entire system large and heavy. In addition, the mechanical inertia should be replaced each time in order to test another elevator system. In this paper, the dynamic load simulation methods using electrical inertia are presented so that the volume and weight of the simulator system are greatly reduced and the adjustment of inertia value can be achieved easily by software. Experimental results show the feasibility of this simulator system.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.
